4Gb: x8, x16 NAND Flash Memory
General Description
General Description
Micron NAND Flash devices include an asynchronous data interface for high-performance I/O operations. These devices use a highly multiplexed 8-bit bus (I/Ox) to transfer
commands, address, and data. There are five control signals used to implement the
asynchronous data interface: CE#, CLE, ALE, WE#, and RE#. Additional signals control
hardware write protection and monitor device status (R/B#).
This hardware interface creates a low pin-count device with a standard pinout that remains the same from one density to another, enabling future upgrades to higher densities with no board redesign.
A target is the unit of memory accessed by a chip enable signal. A target contains one or
more NAND Flash die. A NAND Flash die is the minimum unit that can independently
execute commands and report status. A NAND Flash die, in the ONFI specification, is
referred to as a logical unit (LUN). There is at least one NAND Flash die per chip enable
signal. For further details, see Device and Array Organization.
Signal Descriptions
Table 1: Signal Definitions
Signal1
Type
Description2
ALE
Input
Address latch enable: Loads an address from I/O[7:0] into the address register.
CE#
Input
Chip enable: Enables or disables one or more die (LUNs) in a target.
CLE
Input
Command latch enable: Loads a command from I/O[7:0] into the command register.
LOCK
Input
When LOCK is HIGH during power-up, the BLOCK LOCK function is enabled. To disable the
BLOCK LOCK, connect LOCK to VSS during power-up, or leave it disconnected (internal
pull-down).
RE#
Input
Read enable: Transfers serial data from the NAND Flash to the host system.
WE#
Input
Write enable: Transfers commands, addresses, and serial data from the host system to the
NAND Flash.
WP#
Input
Write protect: Enables or disables array PROGRAM and ERASE operations.
I/O[7:0] (x8)
I/O[15:0] (x16)
I/O
Data inputs/outputs: The bidirectional I/Os transfer address, data, and command information.
R/B#
Output
Ready/busy: An open-drain, active-low output that requires an external pull-up resistor.
This signal indicates target array activity.
VCC
Supply
VCC: Core power supply
VSS
Supply
VSS: Core ground connection
NC
–
No connect: NCs are not internally connected. They can be driven or left unconnected.
DNU
–
Do not use: DNUs must be left unconnected.

Architecture
Architecture
These devices use NAND Flash electrical and command interfaces. Data, commands,
and addresses are multiplexed onto the same pins and received by I/O control circuits.
The commands received at the I/O control circuits are latched by a command register
and are transferred to control logic circuits for generating internal signals to control device operations. The addresses are latched by an address register and sent to a row decoder to select a row address, or to a column decoder to select a column address.
Data is transferred to or from the NAND Flash memory array, byte by byte (x8) or word
by word (x16), through a data register and a cache register.
The NAND Flash memory array is programmed and read using page-based operations
and is erased using block-based operations. During normal page operations, the data
and cache registers act as a single register. During cache operations, the data and cache
registers operate independently to increase data throughput. The status register reports
the status of die operations.

Asynchronous Interface Bus Operation
Asynchronous Interface Bus Operation
The bus on the device is multiplexed. Data I/O, addresses, and commands all share the
same pins. I/O[15:8] are used only for data in the x16 configuration. Addresses and
commands are always supplied on I/O[7:0].
The command sequence typically consists of a COMMAND LATCH cycle, address input
cycles, and one or more data cycles, either READ or WRITE.

or VIL.
2. WP# should be biased to CMOS LOW or HIGH for standby.
Asynchronous Enable/Standby
When the device is not performing an operation, the CE# pin is typically driven HIGH
and the device enters standby mode. The memory will enter standby if CE# goes HIGH
while data is being transferred and the device is not busy. This helps reduce power consumption.
The CE# “Don’t Care” operation enables the NAND Flash to reside on the same asynchronous memory bus as other Flash or SRAM devices. Other devices on the memory
bus can then be accessed while the NAND Flash is busy with internal operations. This
capability is important for designs that require multiple NAND Flash devices on the
same bus.
A HIGH CLE signal indicates that a command cycle is taking place. A HIGH ALE signal
signifies that an ADDRESS INPUT cycle is occurring.
Asynchronous Commands
An asynchronous command is written from I/O[7:0] to the command register on the rising edge of WE# when CE# is LOW, ALE is LOW, CLE is HIGH, and RE# is HIGH.
Commands are typically ignored by die (LUNs) that are busy (RDY = 0); however, some
commands, including READ STATUS (70h) and READ STATUS ENHANCED (78h), are
accepted by die (LUNs) even when they are busy.
For devices with a x16 interface, I/O[15:8] must be written with zeros when a command
is issued.

Asynchronous Addresses
An asynchronous address is written from I/O[7:0] to the address register on the rising
edge of WE# when CE# is LOW, ALE is HIGH, CLE is LOW, and RE# is HIGH.
Bits that are not part of the address space must be LOW (see Device and Array Organization). The number of cycles required for each command varies. Refer to the command
descriptions to determine addressing requirements.
Addresses are typically ignored by die (LUNs) that are busy (RDY = 0); however, some
addresses are accepted by die (LUNs) even when they are busy; for example, like address cycles that follow the READ STATUS ENHANCED (78h) command.

Asynchronous Data Output
Data can be output from a die (LUN) if it is in a READY state. Data output is supported
following a READ operation from the NAND Flash array. Data is output from the cache
register of the selected die (LUN) to I/O[7:0] on the falling edge of RE# when CE# is
LOW, ALE is LOW, CLE is LOW, and WE# is HIGH.
If the host controller is using a tRC of 30ns or greater, the host can latch the data on the
rising edge of RE# (see the figure below for proper timing). If the host controller is using
a tRC of less than 30ns, the host can latch the data on the next falling edge of RE#.
Using the READ STATUS ENHANCED (78h) command prevents data contention following an interleaved die (multi-LUN) operation. After issuing the READ STATUS ENHANCED (78h) command, to enable data output, issue the READ MODE (00h) command.
Data output requests are typically ignored by a die (LUN) that is busy (RDY = 0); however, it is possible to output data from the status register even when a die (LUN) is busy by
first issuing the READ STATUS or READ STATUS ENHANCED (78h) command.

Write Protect#
The write protect# (WP#) signal enables or disables PROGRAM and ERASE operations
to a target. When WP# is LOW, PROGRAM and ERASE operations are disabled. When
WP# is HIGH, PROGRAM and ERASE operations are enabled.
It is recommended that the host drive WP# LOW during power-on until V CC is stable to
prevent inadvertent PROGRAM and ERASE operations (see Device Initialization for additional details).
WP# must be transitioned only when the target is not busy and prior to beginning a
command sequence. After a command sequence is complete and the target is ready,
WP# can be transitioned. After WP# is transitioned, the host must wait tWW before issuing a new command.
The WP# signal is always an active input, even when CE# is HIGH. This signal should
not be multiplexed with other signals.
Ready/Busy#
The ready/busy# (R/B#) signal provides a hardware method of indicating whether a target is ready or busy. A target is busy when one or more of its die (LUNs) are busy
(RDY = 0). A target is ready when all of its die (LUNs) are ready (RDY = 1). Because each
die (LUN) contains a status register, it is possible to determine the independent status
of each die (LUN) by polling its status register instead of using the R/B# signal (see Status Operations for details regarding die (LUN) status).
This signal requires a pull-up resistor, Rp, for proper operation. R/B# is HIGH when the
target is ready, and transitions LOW when the target is busy. The signal's open-drain

driver enables multiple R/B# outputs to be OR-tied. Typically, R/B# is connected to an
interrupt pin on the system controller.
The combination of Rp and capacitive loading of the R/B# circuit determines the rise
time of the R/B# signal. The actual value used for Rp depends on the system timing requirements. Large values of Rp cause R/B# to be delayed significantly. Between the 10%
and 90% points on the R/B# waveform, the rise time is approximately two time constants (TC).
TC = R × C
Where R = Rp (resistance of pull-up resistor), and C = total capacitive load.
The fall time of the R/B# signal is determined mainly by the output impedance of the
R/B# signal and the total load capacitance. Approximate Rp values using a circuit load
of 100pF are provided in Figure 20 (page 26).
The minimum value for Rp is determined by the output drive capability of the R/B# signal, the output voltage swing, and V CC.

Where ΣIL is the sum of the input currents of all devices tied to the R/B# pin.

Device Initialization
Device Initialization
Micron NAND Flash devices are designed to prevent data corruption during power
transitions. V CC is internally monitored. (The WP# signal supports additional hardware
protection during power transitions.) When ramping V CC, use the following procedure
to initialize the device:
1. Ramp V CC.
2. The host must wait for R/B# to be valid and HIGH before issuing RESET (FFh) to
any target. The R/B# signal becomes valid when 50µs has elapsed since the beginning the V CC ramp, and 10µs has elapsed since V CC reaches V CC (MIN).
3. If not monitoring R/B#, the host must wait at least 100µs after V CC reaches V CC
(MIN). If monitoring R/B#, the host must wait until R/B# is HIGH.
4. The asynchronous interface is active by default for each target. Each LUN draws
less than an average of 10mA (IST) measured over intervals of 1ms until the RESET
(FFh) command is issued.
5. The RESET (FFh) command must be the first command issued to all targets (CE#s)
after the NAND Flash device is powered on. Each target will be busy for 1ms after a
RESET command is issued. The RESET busy time can be monitored by polling
R/B# or issuing the READ STATUS (70h) command to poll the status register.
6. The device is now initialized and ready for normal operation.

Reset Operations
Reset Operations
RESET (FFh)
The RESET command is used to put the memory device into a known condition and to
abort the command sequence in progress.
READ, PROGRAM, and ERASE commands can be aborted while the device is in the busy
state. The contents of the memory location being programmed or the block being
erased are no longer valid. The data may be partially erased or programmed, and is invalid. The command register is cleared and is ready for the next command. The data
register and cache register contents are marked invalid.
The status register contains the value E0h when WP# is HIGH; otherwise it is written
with a 60h value. R/B# goes LOW for tRST after the RESET command is written to the
command register.
The RESET command must be issued to all CE#s as the first command after power-on.
The device will be busy for a maximum of 1ms.

READ ID (90h)
The READ ID (90h) command is used to read identifier codes programmed into the target. This command is accepted by the target only when all die (LUNs) on the target are
idle.
Writing 90h to the command register puts the target in read ID mode. The target stays in
this mode until another valid command is issued.
When the 90h command is followed by an 00h address cycle, the target returns a 5-byte
identifier code that includes the manufacturer ID, device configuration, and part-specific information.
When the 90h command is followed by a 20h address cycle, the target returns the 4-byte
ONFI identifier code.

READ PARAMETER PAGE (ECh)
READ PARAMETER PAGE (ECh)
The READ PARAMETER PAGE (ECh) command is used to read the ONFI parameter page
programmed into the target. This command is accepted by the target only when all die
(LUNs) on the target are idle.
Writing ECh to the command register puts the target in read parameter page mode. The
target stays in this mode until another valid command is issued.
When the ECh command is followed by an 00h address cycle, the target goes busy for tR.
If the READ STATUS (70h) command is used to monitor for command completion, the
READ MODE (00h) command must be used to re-enable data output mode. Use of the
READ STATUS ENHANCED (78h) command is prohibited while the target is busy and
during data output.
A minimum of three copies of the parameter page are stored in the device. Each parameter page is 256 bytes. If desired, the RANDOM DATA READ (05h-E0h) command can be
used to change the location of data output.

READ UNIQUE ID (EDh)
READ UNIQUE ID (EDh)
The READ UNIQUE ID (EDh) command is used to read a unique identifier programmed
into the target. This command is accepted by the target only when all die (LUNs) on the
target are idle.
Writing EDh to the command register puts the target in read unique ID mode. The target stays in this mode until another valid command is issued.
When the EDh command is followed by an 00h address cycle, the target goes busy for
If the READ STATUS (70h) command is used to monitor for command completion,
the READ MODE (00h) command must be used to re-enable data output mode.
tR.
After tR completes, the host enables data output mode to read the unique ID. When the
asynchronous interface is active, one data byte is output per RE# toggle.
Sixteen copies of the unique ID data are stored in the device. Each copy is 32 bytes. The
first 16 bytes of a 32-byte copy are unique data, and the second 16 bytes are the complement of the first 16 bytes. The host should XOR the first 16 bytes with the second 16
bytes. If the result is 16 bytes of FFh, then that copy of the unique ID data is correct. In
the event that a non-FFh result is returned, the host can repeat the XOR operation on a
subsequent copy of the unique ID data. If desired, the RANDOM DATA READ (05h-E0h)
command can be used to change the data output location.
The upper eight I/Os on a x16 device are not used and are a “Don’t Care” for x16 devices.

Feature Operations
The SET FEATURES (EFh) and GET FEATURES (EEh) commands are used to modify the
target's default power-on behavior. These commands use a one-byte feature address to
determine which subfeature parameters will be read or modified. Each feature address
(in the 00h to FFh range) is defined in below. The SET FEATURES (EFh) command
writes subfeature parameters (P1–P4) to the specified feature address. The GET FEATURES command reads the subfeature parameters (P1–P4) at the specified feature address.

Feature Operations
Writing EFh to the command register puts the target in the set features mode. The target
stays in this mode until another command is issued.
The EFh command is followed by a valid feature address. The host waits for tADL before
the subfeature parameters are input. When the asynchronous interface is active, one
subfeature parameter is latched per rising edge of WE#.
After all four subfeature parameters are input, the target goes busy for tFEAT. The READ
STATUS (70h) command can be used to monitor for command completion.
Feature address 01h (timing mode) operation is unique. If SET FEATURES is used to
modify the interface type, the target will be busy for tITC.

Status Operations
Status Operations
Each die (LUN) provides its status independently of other die (LUNs) on the same target
through its 8-bit status register.
After the READ STATUS (70h) or READ STATUS ENHANCED (78h) command is issued,
status register output is enabled. The contents of the status register are returned on I/
O[7:0] for each data output request.
When the asynchronous interface is active and status register output is enabled,
changes in the status register are seen on I/O[7:0] as long as CE# and RE# are LOW; it is
not necessary to toggle RE# to see the status register update.
While monitoring the status register to determine when a data transfer from the Flash
array to the data register (tR) is complete, the host must issue the READ MODE (00h)
command to disable the status register and enable data output (see Read Operations).
The READ STATUS (70h) command returns the status of the most recently selected die
(LUN). To prevent data contention during or following an interleaved die (multi-LUN)
operation, the host must enable only one die (LUN) for status output by using the READ
STATUS ENHANCED (78h) command (see Interleaved Die (Multi-LUN) Operations).

Status Operations
If there is only one die (LUN) per target, the READ STATUS (70h) command can be used
to return status following any NAND command.
In devices that have more than one die (LUN) per target, during and following interleaved die (multi-LUN) operations, the READ STATUS ENHANCED (78h) command
must be used to select the die (LUN) that should report status. In this situation, using
the READ STATUS (70h) command will result in bus contention, as two or more die
(LUNs) could respond until the next operation is issued. The READ STATUS (70h) command can be used following all single die (LUN) operations.

READ STATUS ENHANCED (78h)
The READ STATUS ENHANCED (78h) command returns the status of the addressed die
(LUN) on a target even when it is busy (RDY = 0). This command is accepted by all die
(LUNs), even when they are BUSY (RDY = 0).
Writing 78h to the command register, followed by three row address cycles containing
the page, block, and LUN addresses, puts the selected die (LUN) into read status mode.
The selected die (LUN) stays in this mode until another valid command is issued. Die
(LUNs) that are not addressed are deselected to avoid bus contention.
The selected LUN's status is returned when the host requests data output. The RDY and
ARDY bits of the status register are shared for all planes on the selected die (LUN). The
FAILC and FAIL bits are specific to the plane specified in the row address.
The READ STATUS ENHANCED (78h) command also enables the selected die (LUN) for
data output. To begin data output following a READ-series operation after the selected
die (LUN) is ready (RDY = 1), issue the READ MODE (00h) command, then begin data
output. If the host needs to change the cache register that will output data, use the
RANDOM DATA READ TWO-PLANE (06h-E0h) command after the die (LUN) is ready.
Use of the READ STATUS ENHANCED (78h) command is prohibited during the poweron RESET (FFh) command and when OTP mode is enabled. It is also prohibited following some of the other reset, identification, and configuration operations. See individual
operations for specific details.

Column Address Operations
Column Address Operations
The column address operations affect how data is input to and output from the cache
registers within the selected die (LUNs). These features provide host flexibility for managing data, especially when the host internal buffer is smaller than the number of data
bytes or words in the cache register.
When the asynchronous interface is active, column address operations can address any
byte in the selected cache register.
RANDOM DATA READ (05h-E0h)
The RANDOM DATA READ (05h-E0h) command changes the column address of the selected cache register and enables data output from the last selected die (LUN). This
command is accepted by the selected die (LUN) when it is ready (RDY = 1; ARDY = 1). It
is also accepted by the selected die (LUN) during CACHE READ operations
(RDY = 1; ARDY = 0).
Writing 05h to the command register, followed by two column address cycles containing
the column address, followed by the E0h command, puts the selected die (LUN) into
data output mode. After the E0h command cycle is issued, the host must wait at least
tWHR before requesting data output. The selected die (LUN) stays in data output mode
until another valid command is issued.
In devices with more than one die (LUN) per target, during and following interleaved
die (multi-LUN) operations, the READ STATUS ENHANCED (78h) command must be
issued prior to issuing the RANDOM DATA READ (05h-E0h). In this situation, using the
RANDOM DATA READ (05h-E0h) command without the READ STATUS ENHANCED
(78h) command will result in bus contention because two or more die (LUNs) could
output data.

Writing 06h to the command register, followed by two column address cycles and three
row address cycles, followed by E0h, enables data output mode on the address LUN’s
cache register at the specified column address. After the E0h command cycle is issued,
the host must wait at least tWHR before requesting data output. The selected die (LUN)
stays in data output mode until another valid command is issued.
Following a two-plane read page operation, the RANDOM DATA READ TWO-PLANE
(06h-E0h) command is used to select the cache register to be enabled for data output.
After data output is complete on the selected plane, the command can be issued again
to begin data output on another plane.
In devices with more than one die (LUN) per target, after all of the die (LUNs) on the
target are ready (RDY = 1), the RANDOM DATA READ TWO-PLANE (06h-E0h) command
can be used following an interleaved die (multi-LUN) read operation. Die (LUNs) that
are not addressed are deselected to avoid bus contention.
In devices with more than one die (LUN) per target, during interleaved die (multi-LUN)
operations where more than one or more die (LUNs) are busy (RDY = 1; ARDY = 0 or
RDY = 0; ARDY = 0), the READ STATUS ENHANCED (78h) command must be issued to
the die (LUN) to be selected prior to issuing the RANDOM DATA READ TWO-PLANE
(06h-E0h). In this situation, using the RANDOM DATA READ TWO-PLANE (06h-E0h)
command without the READ STATUS ENHANCED (78h) command will result in bus
contention, as two or more die (LUNs) could output data.
If there is a need to update the column address without selecting a new cache register
or LUN, the RANDOM DATA READ (05h-E0h) command can be used instead.

RANDOM DATA INPUT (85h)
The RANDOM DATA INPUT (85h) command changes the column address of the selected cache register and enables data input on the last-selected die (LUN). This command
is accepted by the selected die (LUN) when it is ready (RDY = 1; ARDY = 1). It is also accepted by the selected die (LUN) during cache program operations
(RDY = 1; ARDY = 0).
Writing 85h to the command register, followed by two column address cycles containing
the column address, puts the selected die (LUN) into data input mode. After the second
address cycle is issued, the host must wait at least tADL before inputting data. The selected die (LUN) stays in data input mode until another valid command is issued.
Though data input mode is enabled, data input from the host is optional. Data input
begins at the column address specified.
The RANDOM DATA INPUT (85h) command is allowed after the required address cycles
are specified, but prior to the final command cycle (10h, 11h, 15h) of the following commands while data input is permitted: PROGRAM PAGE (80h-10h), PROGRAM PAGE
CACHE (80h-15h), PROGRAM FOR INTERNAL DATA MOVE (85h-10h), and PROGRAM
FOR TWO-PLANE INTERNAL DATA MOVE (85h-11h).
In devices that have more than one die (LUN) per target, the RANDOM DATA INPUT
(85h) command can be used with other commands that support interleaved die (multiLUN) operations.

Column Address Operations
PROGRAM FOR INTERNAL DATA INPUT (85h)
The PROGRAM FOR INTERNAL DATA INPUT (85h) command changes the row address
(block and page) where the cache register contents will be programmed in the NAND
Flash array. It also changes the column address of the selected cache register and enables data input on the specified die (LUN). This command is accepted by the selected
die (LUN) when it is ready (RDY = 1; ARDY = 1). It is also accepted by the selected die
(LUN) during cache programming operations (RDY = 1; ARDY = 0).
Write 85h to the command register. Then write two column address cycles and three
row address cycles. This updates the page and block destination of the selected device
for the addressed LUN and puts the cache register into data input mode. After the fifth
address cycle is issued the host must wait at least tADL before inputting data. The selected LUN stays in data input mode until another valid command is issued. Though data
input mode is enabled, data input from the host is optional. Data input begins at the
column address specified.
The PROGRAM FOR INTERNAL DATA INPUT (85h) command is allowed after the required address cycles are specified, but prior to the final command cycle (10h, 11h, 15h)
of the following commands while data input is permitted: PROGRAM PAGE (80h-10h),
PROGRAM PAGE TWO-PLANE (80h-11h), PROGRAM PAGE CACHE (80h-15h), PROGRAM FOR INTERNAL DATA MOVE (85h-10h), and PROGRAM FOR TWO-PLANE INTERNAL DATA MOVE (85h-11h). When used with these commands, the LUN address
and plane select bits are required to be identical to the LUN address and plane select
bits originally specified.
The PROGRAM FOR INTERNAL DATA INPUT (85h) command enables the host to modify the original page and block address for the data in the cache register to a new page
and block address.
In devices that have more than one die (LUN) per target, the PROGRAM FOR INTERNAL
DATA INPUT (85h) command can be used with other commands that support interleaved die (multi-LUN) operations.
The PROGRAM FOR INTERNAL DATA INPUT (85h) command can be used with the
RANDOM DATA READ (05h-E0h) or RANDOM DATA READ TWO-PLANE (06h-E0h)
commands to read and modify cache register contents in small sections prior to programming cache register contents to the NAND Flash array. This capability can reduce
the amount of buffer memory used in the host controller.
The RANDOM DATA INPUT (85h) command can be used during the PROGRAM FOR
INTERNAL DATA MOVE command sequence to modify one or more bytes of the original data. First, data is copied into the cache register using the 00h-35h command sequence, then the RANDOM DATA INPUT (85h) command is written along with the address of the data to be modified next. New data is input on the external data pins. This
copies the new data into the cache register.

Read Operations
Read Operations
The READ PAGE (00h-30h) command, when issued by itself, reads one page from the
NAND Flash array to its cache register and enables data output for that cache register.
During data output the following commands can be used to read and modify the data in
the cache registers: RANDOM DATA READ (05h-E0h) and RANDOM DATA INPUT (85h).
Read Cache Operations
To increase data throughput, the READ PAGE CACHE series (31h, 00h-31h) commands
can be used to output data from the cache register while concurrently copying a page
from the NAND Flash array to the data register.
To begin a read page cache sequence, begin by reading a page from the NAND Flash array to its corresponding cache register using the READ PAGE (00h-30h) command.
R/B# goes LOW during tR and the selected die (LUN) is busy (RDY = 0, ARDY = 0). After
tR (R/B# is HIGH and RDY = 1, ARDY = 1), issue either of these commands:
• READ PAGE CACHE SEQUENTIAL (31h) – copies the next sequential page from the
NAND Flash array to the data register
• READ PAGE CACHE RANDOM (00h-31h) – copies the page specified in this command
from the NAND Flash array to its corresponding data register
After the READ PAGE CACHE series (31h, 00h-31h) command has been issued, R/B#
goes LOW on the target, and RDY = 0 and ARDY = 0 on the die (LUN) for tRCBSY while
the next page begins copying data from the array to the data register. After tRCBSY,
R/B# goes HIGH and the die’s (LUN’s) status register bits indicate the device is busy
with a cache operation (RDY = 1, ARDY = 0). The cache register becomes available and
the page requested in the READ PAGE CACHE operation is transferred to the data register. At this point, data can be output from the cache register, beginning at column address 0. The RANDOM DATA READ (05h-E0h) command can be used to change the column address of the data output by the die (LUN).
After outputting the desired number of bytes from the cache register, either an additional READ PAGE CACHE series (31h, 00h-31h) operation can be started or the READ
PAGE CACHE LAST (3Fh) command can be issued.
If the READ PAGE CACHE LAST (3Fh) command is issued, R/B# goes LOW on the target,
and RDY = 0 and ARDY = 0 on the die (LUN) for tRCBSY while the data register is copied
into the cache register. After tRCBSY, R/B# goes HIGH and RDY = 1 and
ARDY = 1, indicating that the cache register is available and that the die (LUN) is ready.
Data can then be output from the cache register, beginning at column address 0. The
RANDOM DATA READ (05h-E0h) command can be used to change the column address
of the data being output.
For READ PAGE CACHE series (31h, 00h-31h, 3Fh), during the die (LUN) busy time,
tRCBSY, when RDY = 0 and ARDY = 0, the only valid commands are status operations
(70h, 78h) and RESET (FFh). When RDY = 1 and ARDY = 0, the only valid commands
during READ PAGE CACHE series (31h, 00h-31h) operations are status operations (70h,
78h), READ MODE (00h), READ PAGE CACHE series (31h, 00h-31h), RANDOM DATA
READ (05h-E0h), and RESET (FFh).

Read Operations
Two-Plane Read Operations
Two-plane read page operations improve data throughput by copying data from more
than one plane simultaneously to the specified cache registers. This is done by prepending one or more READ PAGE TWO-PLANE (00h-00h-30h) commands in front of
the READ PAGE (00h-30h) command.
When the die (LUN) is ready, the RANDOM DATA READ TWO-PLANE (06h-E0h) command determines which plane outputs data. During data output, the following commands can be used to read and modify the data in the cache registers: RANDOM DATA
READ (05h-E0h) and RANDOM DATA INPUT (85h).
Two-Plane Read Cache Operations
Two-plane read cache operations can be used to output data from more than one cache
register while concurrently copying one or more pages from the NAND Flash array to
the data register. This is done by prepending READ PAGE TWO-PLANE (00h-00h-30h)
commands in front of the PAGE READ CACHE RANDOM (00h-31h) command.
To begin a two-plane read page cache sequence, begin by issuing a READ PAGE TWOPLANE operation using the READ PAGE TWO-PLANE (00h-00h-30h) and READ PAGE
(00h-30h) commands. R/B# goes LOW during tR and the selected die (LUN) is busy
(RDY = 0, ARDY = 0). After tR (R/B# is HIGH and RDY = 1, ARDY = 1), issue either of these
commands:
• READ PAGE CACHE SEQUENTIAL (31h) – copies the next sequential pages from the
previously addressed planes from the NAND Flash array to the data registers.
• READ PAGE TWO-PLANE (00h-00h-30h) [in some cases, followed by READ PAGE
CACHE RANDOM (00h-31h)] – copies the pages specified from the NAND Flash array
to the corresponding data registers.
After the READ PAGE CACHE series (31h, 00h-31h) command has been issued, R/B#
goes LOW on the target, and RDY = 0 and ARDY = 0 on the die (LUN) for tRCBSY while
the next pages begin copying data from the array to the data registers. After tRCBSY,
R/B# goes HIGH and the LUN’s status register bits indicate the device is busy with a
cache operation (RDY = 1, ARDY = 0). The cache registers become available and the pages requested in the READ PAGE CACHE operation are transferred to the data registers.
Issue the RANDOM DATA READ TWO-PLANE (06h-E0h) command to determine which
cache register will output data. After data is output, the RANDOM DATA READ TWOPLANE (06h-E0h) command can be used to output data from other cache registers. After a cache register has been selected, the RANDOM DATA READ (05h-E0h) command
can be used to change the column address of the data output.
After outputting data from the cache registers, either an additional TWO-PLANE READ
CACHE series (31h, 00h-31h) operation can be started or the READ PAGE CACHE LAST
(3Fh) command can be issued.
If the READ PAGE CACHE LAST (3Fh) command is issued, R/B# goes LOW on the target,
and RDY = 0 and ARDY = 0 on the die (LUN) for tRCBSY while the data registers are copied into the cache registers. After tRCBSY, R/B# goes HIGH and RDY = 1 and ARDY = 1,
indicating that the cache registers are available and that the die (LUN) is ready. Issue the
RANDOM DATA READ TWO-PLANE (06h-E0h) command to determine which cache
register will output data. After data is output, the RANDOM DATA READ TWO-PLANE
(06h-E0h) command can be used to output data from other cache registers. After a
cache register has been selected, the RANDOM DATA READ (05h-E0h) command can
be used to change the column address of the data output.

Read Operations
For READ PAGE CACHE series (31h, 00h-31h, 3Fh), during the die (LUN) busy time,
tRCBSY, when RDY = 0 and ARDY = 0, the only valid commands are status operations
(70h, 78h) and RESET (FFh). When RDY = 1 and ARDY = 0, the only valid commands
during READ PAGE CACHE series (31h, 00h-31h) operations are status operations (70h,
78h), READ MODE (00h), two-plane read cache series (31h, 00h-00h-30h, 00h-31h),
RANDOM DATA READ (06h-E0h, 05h-E0h), and RESET (FFh).
READ MODE (00h)
The READ MODE (00h) command disables status output and enables data output for
the last-selected die (LUN) and cache register after a READ operation (00h-30h,
00h-3Ah, 00h-35h) has been monitored with a status operation (70h, 78h). This command is accepted by the die (LUN) when it is ready (RDY = 1, ARDY = 1). It is also accepted by the die (LUN) during READ PAGE CACHE (31h, 00h-31h) operations
(RDY = 1 and ARDY = 0).
In devices that have more than one die (LUN) per target, during and following interleaved die (multi-LUN) operations, the READ STATUS ENHANCED (78h) command
must be used to select only one die (LUN) prior to issuing the READ MODE (00h) command. This prevents bus contention.
READ PAGE (00h-30h)
The READ PAGE (00h–30h) command copies a page from the NAND Flash array to its
respective cache register and enables data output. This command is accepted by the die
(LUN) when it is ready (RDY = 1, ARDY = 1).
To read a page from the NAND Flash array, write the 00h command to the command
register, then write n address cycles to the address registers, and conclude with the 30h
command. The selected die (LUN) will go busy (RDY = 0, ARDY = 0) for tR as data is
transferred.
To determine the progress of the data transfer, the host can monitor the target's R/B#
signal or, alternatively, the status operations (70h, 78h) can be used. If the status operations are used to monitor the LUN's status, when the die (LUN) is ready
(RDY = 1, ARDY = 1), the host disables status output and enables data output by issuing
the READ MODE (00h) command. When the host requests data output, output begins
at the column address specified.
During data output the RANDOM DATA READ (05h-E0h) command can be issued.
In devices that have more than one die (LUN) per target, during and following interleaved die (multi-LUN) operations the READ STATUS ENHANCED (78h) command
must be used to select only one die (LUN) prior to the issue of the READ MODE (00h)
command. This prevents bus contention.
The READ PAGE (00h-30h) command is used as the final command of a two-plane read
operation. It is preceded by one or more READ PAGE TWO-PLANE (00h-00h-30h) commands. Data is transferred from the NAND Flash array for all of the addressed planes to
their respective cache registers. When the die (LUN) is ready
(RDY = 1, ARDY = 1), data output is enabled for the cache register linked to the plane
addressed in the READ PAGE (00h-30h) command. When the host requests data output,
output begins at the column address last specified in the READ PAGE (00h-30h) command. The RANDOM DATA READ TWO-PLANE (06h-E0h) command is used to enable
data output in the other cache registers.

READ PAGE CACHE SEQUENTIAL (31h)
The READ PAGE CACHE SEQUENTIAL (31h) command reads the next sequential page
within a block into the data register while the previous page is output from the cache
register. This command is accepted by the die (LUN) when it is ready
(RDY = 1, ARDY = 1). It is also accepted by the die (LUN) during READ PAGE CACHE
(31h, 00h-31h) operations (RDY = 1 and ARDY = 0).
To issue this command, write 31h to the command register. After this command is issued, R/B# goes LOW and the die (LUN) is busy (RDY = 0, ARDY = 0) for tRCBSY. After
tRCBSY, R/B# goes HIGH and the die (LUN) is busy with a cache operation
(RDY = 1, ARDY = 0), indicating that the cache register is available and that the specified
page is copying from the NAND Flash array to the data register. At this point, data can
be output from the cache register beginning at column address 0. The RANDOM DATA
READ (05h-E0h) command can be used to change the column address of the data being
output from the cache register.
The READ PAGE CACHE SEQUENTIAL (31h) command can be used to cross block
boundaries. If the READ PAGE CACHE SEQUENTIAL (31h) command is issued after the
last page of a block is read into the data register, the next page read will be the next logical block in which the 31h command was issued. Do not issue the READ PAGE CACHE
SEQUENTIAL (31h) to cross die (LUN) boundaries. Instead, issue the READ PAGE
CACHE LAST (3Fh) command.

READ PAGE CACHE RANDOM (00h-31h)
The READ PAGE CACHE RANDOM (00h-31h) command reads the specified block and
page into the data register while the previous page is output from the cache register.
This command is accepted by the die (LUN) when it is ready (RDY = 1, ARDY = 1). It is
also accepted by the die (LUN) during READ PAGE CACHE (31h, 00h-31h) operations
(RDY = 1 and ARDY = 0).
To issue this command, write 00h to the command register, then write n address cycles
to the address register, and conclude by writing 31h to the command register. The column address in the address specified is ignored. The die (LUN) address must match the
same die (LUN) address as the previous READ PAGE (00h-30h) command or, if applicable, the previous READ PAGE CACHE RANDOM (00h-31h) command.
After this command is issued, R/B# goes LOW and the die (LUN) is busy
(RDY = 0, ARDY = 0) for tRCBSY. After tRCBSY, R/B# goes HIGH and the die (LUN) is busy
with a cache operation (RDY = 1, ARDY = 0), indicating that the cache register is available and that the specified page is copying from the NAND Flash array to the data register. At this point, data can be output from the cache register beginning at column address 0. The RANDOM DATA READ (05h-E0h) command can be used to change the column address of the data being output from the cache register.
In devices that have more than one die (LUN) per target, during and following interleaved die (multi-LUN) operations the READ STATUS ENHANCED (78h) command followed by the READ MODE (00h) command must be used to select only one die (LUN)
and prevent bus contention.

READ PAGE CACHE LAST (3Fh)
The READ PAGE CACHE LAST (3Fh) command ends the read page cache sequence and
copies a page from the data register to the cache register. This command is accepted by
the die (LUN) when it is ready (RDY = 1, ARDY = 1). It is also accepted by the die (LUN)
during READ PAGE CACHE (31h, 00h-31h) operations (RDY = 1 and ARDY = 0).
To issue the READ PAGE CACHE LAST (3Fh) command, write 3Fh to the command register. After this command is issued, R/B# goes LOW and the die (LUN) is busy
(RDY = 0, ARDY = 0) for tRCBSY. After tRCBSY, R/B# goes HIGH and the die (LUN) is
ready (RDY = 1, ARDY = 1). At this point, data can be output from the cache register, beginning at column address 0. The RANDOM DATA READ (05h-E0h) command can be
used to change the column address of the data being output from the cache register.
In devices that have more than one LUN per target, during and following interleaved die
(multi-LUN) operations the READ STATUS ENHANCED (78h) command followed by
the READ MODE (00h) command must be used to select only one die (LUN) and prevent bus contention.

Read Operations
READ PAGE TWO-PLANE 00h-00h-30h
The READ PAGE TWO-PLANE (00h-00h-30h) operation is similar to the PAGE READ
(00h-30h) operation. It transfers two pages of data from the NAND Flash array to the data registers. Each page must be from a different plane on the same die.
To enter the READ PAGE TWO-PLANE mode, write the 00h command to the command
register, and then write five address cycles for plane 0 (BA6 = 0). Next, write the 00h
command to the command register, and five address cycles for plane 1 (BA6 = 1). Finally, issue the 30h command. The first-plane and second-plane addresses must meet the
two-plane addressing requirements, and, in addition, they must have identical column
addresses.
After the 30h command is written, page data is transferred from both planes to their respective data registers in tR. During these transfers, R/B# goes LOW. When the transfers
are complete, R/B# goes HIGH. To read out the data from the plane 0 data register,
pulse RE# repeatedly. After the data cycle from the plane 0 address completes, issue a
RANDOM DATA READ TWO-PLANE (06h-E0h) command to select the plane 1 address,
then repeatedly pulse RE# to read out the data from the plane 1 data register.
Alternatively, the READ STATUS (70h) command can monitor data transfers. When the
transfers are complete, status register bit 6 is set to 1. To read data from the first of the
two planes, the user must first issue the RANDOM DATA READ TWO-PLANE (06h-E0h)
command and pulse RE# repeatedly.
When the data cycle is complete, issue a RANDOM DATA READ TWO-PLANE (06h-E0h)
command to select the other plane. To output the data beginning at the specified column address, pulse RE# repeatedly.
Use of the READ STATUS ENHANCED (78h) command is prohibited during and following a PAGE READ TWO-PLANE operation.

Program Operations
Program Operations
Program operations are used to move data from the cache or data registers to the NAND
array. During a program operation the contents of the cache and/or data registers are
modified by the internal control logic.
Within a block, pages must be programmed sequentially from the least significant page
address to the most significant page address (0, 1, 2, ….., 63). During a program operation, the contents of the cache and/or data registers are modified by the internal control
logic.
Program Operations
The PROGRAM PAGE (80h-10h) command, when not preceded by the PROGRAM PAGE
TWO-PLANE (80h-11h) command, programs one page from the cache register to the
NAND Flash array. When the die (LUN) is ready (RDY = 1, ARDY = 1), the host should
check the FAIL bit to verify that the operation has completed successfully.
Program Cache Operations
The PROGRAM PAGE CACHE (80h-15h) command can be used to improve program operation system performance. When this command is issued, the die (LUN) goes busy
(RDY = 0, ARDY = 0) while the cache register contents are copied to the data register,
and the die (LUN) is busy with a program cache operation (RDY = 1, ARDY = 0. While
the contents of the data register are moved to the NAND Flash array, the cache register
is available for an additional PROGRAM PAGE CACHE (80h-15h) or PROGRAM PAGE
(80h-10h) command.
For PROGRAM PAGE CACHE series (80h-15h) operations, during the die (LUN) busy
times, tCBSY and tLPROG, when RDY = 0 and ARDY = 0, the only valid commands are
status operations (70h, 78h) and reset (FFh). When RDY = 1 and ARDY = 0, the only valid
commands during PROGRAM PAGE CACHE series (80h-15h) operations are status operations (70h, 78h), PROGRAM PAGE CACHE (80h-15h), PROGRAM PAGE (80h-10h),
RANDOM DATA INPUT (85h), PROGRAM FOR INTERNAL DATA INPUT (85h), and RESET (FFh).
Two-Plane Program Operations
The PROGRAM PAGE TWO-PLANE (80h-11h) command can be used to improve program operation system performance by enabling multiple pages to be moved from the
cache registers to different planes of the NAND Flash array. This is done by prepending
one or more PROGRAM PAGE TWO-PLANE (80h-11h) commands in front of the PROGRAM PAGE (80h-10h) command.
Two-Plane Program Cache Operations
The PROGRAM PAGE TWO-PLANE (80h-11h) command can be used to improve program cache operation system performance by enabling multiple pages to be moved

Program Operations
PROGRAM PAGE (80h-10h)
The PROGRAM PAGE (80h-10h) command enables the host to input data to a cache register, and moves the data from the cache register to the specified block and page address in the array of the selected die (LUN). This command is accepted by the die (LUN)
when it is ready (RDY = 1, ARDY = 1). It is also accepted by the die (LUN) when it is busy
with a PROGRAM PAGE CACHE (80h-15h) operation (RDY = 1, ARDY = 0).
To input a page to the cache register and move it to the NAND array at the block and
page address specified, write 80h to the command register. Unless this command has
been preceded by a PROGRAM PAGE TWO-PLANE (80h-11h) command, issuing the 80h
to the command register clears all of the cache registers' contents on the selected target.
Then write n address cycles containing the column address and row address. Data input
cycles follow. Serial data is input beginning at the column address specified. At any time
during the data input cycle the RANDOM DATA INPUT (85h) and PROGRAM FOR INTERNAL DATA INPUT (85h) commands may be issued. When data input is complete,
write 10h to the command register. The selected LUN will go busy
(RDY = 0, ARDY = 0) for tPROG as data is transferred.
To determine the progress of the data transfer, the host can monitor the target's R/B#
signal or, alternatively, the status operations (70h, 78h) may be used. When the die
(LUN) is ready (RDY = 1, ARDY = 1), the host should check the status of the FAIL bit.
In devices that have more than one die (LUN) per target, during and following interleaved die (multi-LUN) operations, the READ STATUS ENHANCED (78h) command
must be used to select only one die (LUN) for status output. Use of the READ STATUS
(70h) command could cause more than one die (LUN) to respond, resulting in bus contention.
The PROGRAM PAGE (80h-10h) command is used as the final command of a two-plane
program operation. It is preceded by one or more PROGRAM PAGE TWO-PLANE
(80h-11h) commands. Data is transferred from the cache registers for all of the addressed planes to the NAND array. The host should check the status of the operation by
using the status operations (70h, 78h).

(LUN) when it is ready (RDY =1, ARDY = 1). It is also accepted by the die (LUN) when
busy with a PROGRAM PAGE CACHE (80h-15h) operation (RDY = 1, ARDY = 0).
To input a page to the cache register to move it to the NAND array at the block and page
address specified, write 80h to the command register. Unless this command has been
preceded by a PROGRAM PAGE TWO-PLANE (80h-11h) command, issuing the 80h to
the command register clears all of the cache registers' contents on the selected target.
Then write n address cycles containing the column address and row address. Data input
cycles follow. Serial data is input beginning at the column address specified. At any time
during the data input cycle the RANDOM DATA INPUT (85h) and PROGRAM FOR INTERNAL DATA INPUT (85h) commands may be issued. When data input is complete,
write 15h to the command register. The selected LUN will go busy
(RDY = 0, ARDY = 0) for tCBSY to allow the data register to become available from a previous program cache operation, to copy data from the cache register to the data register,
and then to begin moving the data register contents to the specified page and block address.
To determine the progress of tCBSY, the host can monitor the target's R/B# signal or, alternatively, the status operations (70h, 78h) can be used. When the LUN’s status shows
that it is busy with a PROGRAM CACHE operation (RDY = 1, ARDY = 0), the host should
check the status of the FAILC bit to see if a previous cache operation was successful.
If, after tCBSY, the host wants to wait for the program cache operation to complete,
without issuing the PROGRAM PAGE (80h-10h) command, the host should monitor ARDY until it is 1. The host should then check the status of the FAIL and FAILC bits.
In devices with more than one die (LUN) per target, during and following interleaved
die (multi-LUN) operations, the READ STATUS ENHANCED (78h) command must be
used to select only one die (LUN) for status output. Use of the READ STATUS (70h) command could cause more than one die (LUN) to respond, resulting in bus contention.
The PROGRAM PAGE CACHE (80h-15h) command is used as the final command of a
two-plane program cache operation. It is preceded by one or more PROGRAM PAGE
TWO-PLANE (80h-11h) commands. Data for all of the addressed planes is transferred
from the cache registers to the corresponding data registers, then moved to the NAND
Flash array. The host should check the status of the operation by using the status operations (70h, 78h).

Program Operations
PROGRAM PAGE TWO-PLANE (80h-11h)
The PROGRAM PAGE TWO-PLANE (80h-11h) command enables the host to input data
to the addressed plane's cache register and queue the cache register to ultimately be
moved to the NAND Flash array. This command can be issued one or more times. Each
time a new plane address is specified that plane is also queued for data transfer. To input data for the final plane and to begin the program operation for all previously
queued planes, issue either the PROGRAM PAGE (80h-10h) command or the PROGRAM
PAGE CACHE (80h-15h) command. All of the queued planes will move the data to the
NAND Flash array. This command is accepted by the die (LUN) when it is ready
(RDY = 1).
To input a page to the cache register and queue it to be moved to the NAND Flash array
at the block and page address specified, write 80h to the command register. Unless this
command has been preceded by a PROGRAM PAGE TWO-PLANE (80h-11h) command,
issuing the 80h to the command register clears all of the cache registers' contents on the
selected target. Write five address cycles containing the column address and row address; data input cycles follow. Serial data is input beginning at the column address
specified. At any time during the data input cycle, the RANDOM DATA INPUT (85h) and
PROGRAM FOR INTERNAL DATA INPUT (85h) commands can be issued. When data
input is complete, write 11h to the command register. The selected die (LUN) will go
busy (RDY = 0, ARDY = 0) for tDBSY.
To determine the progress of tDBSY, the host can monitor the target's R/B# signal or,
alternatively, the status operations (70h, 78h) can be used. When the LUN's status
shows that it is ready (RDY = 1), additional PROGRAM PAGE TWO-PLANE (80h-11h)
commands can be issued to queue additional planes for data transfer. Alternatively, the
PROGRAM PAGE (80h-10h) or PROGRAM PAGE CACHE (80h-15h) commands can be issued.
When the PROGRAM PAGE (80h-10h) command is used as the final command of a twoplane program operation, data is transferred from the cache registers to the NAND
Flash array for all of the addressed planes during tPROG. When the die (LUN) is ready
(RDY = 1, ARDY = 1), the host should check the status of the FAIL bit for each of the
planes to verify that programming completed successfully.
When the PROGRAM PAGE CACHE (80h-15h) command is used as the final command
of a program cache two-plane operation, data is transferred from the cache registers to
the data registers after the previous array operations finish. The data is then moved
from the data registers to the NAND Flash array for all of the addressed planes. This occurs during tCBSY. After tCBSY, the host should check the status of the FAILC bit for
each of the planes from the previous program cache operation, if any, to verify that programming completed successfully.
For the PROGRAM PAGE TWO-PLANE (80h-11h), PROGRAM PAGE (80h-10h), and PROGRAM PAGE CACHE (80h-15h) commands, see Two-Plane Operations for two-plane addressing requirements.

Erase Operations
Erase Operations
Erase operations are used to clear the contents of a block in the NAND Flash array to
prepare its pages for program operations.
Erase Operations
The ERASE BLOCK (60h-D0h) command, when not preceded by the ERASE BLOCK
TWO-PLANE (60h-D1h) command, erases one block in the NAND Flash array. When the
die (LUN) is ready (RDY = 1, ARDY = 1), the host should check the FAIL bit to verify that
this operation completed successfully.
TWO-PLANE ERASE Operations
The ERASE BLOCK TWO-PLANE (60h-D1h) command can be used to further system
performance of erase operations by allowing more than one block to be erased in the
NAND array. This is done by prepending one or more ERASE BLOCK TWO-PLANE (60hD1h) commands in front of the ERASE BLOCK (60h-D0h) command. See Two-Plane
Operations for details.
ERASE BLOCK (60h-D0h)
The ERASE BLOCK (60h-D0h) command erases the specified block in the NAND Flash
array. This command is accepted by the die (LUN) when it is ready (RDY = 1, ARDY = 1).
To erase a block, write 60h to the command register. Then write three address cycles
containing the row address; the page address is ignored. Conclude by writing D0h to the
command register. The selected die (LUN) will go busy (RDY = 0, ARDY = 0) for tBERS
while the block is erased.
To determine the progress of an ERASE operation, the host can monitor the target's
R/B# signal, or alternatively, the status operations (70h, 78h) can be used. When the die
(LUN) is ready (RDY = 1, ARDY = 1) the host should check the status of the FAIL bit.

ERASE BLOCK TWO-PLANE (60h-D1h)
The ERASE BLOCK TWO-PLANE (60h-D1h) command queues a block in the specified
plane to be erased in the NAND Flash array. This command can be issued one or more
times. Each time a new plane address is specified, that plane is also queued for a block
to be erased. To specify the final block to be erased and to begin the ERASE operation
for all previously queued planes, issue the ERASE BLOCK (60h-D0h) command. This
command is accepted by the die (LUN) when it is ready (RDY = 1, ARDY = 1).
To queue a block to be erased, write 60h to the command register, then write three address cycles containing the row address; the page address is ignored. Conclude by writing D1h to the command register. The selected die (LUN) will go busy (RDY = 0, ARDY =
0) for tDBSY.
To determine the progress of tDBSY, the host can monitor the target's R/B# signal, or
alternatively, the status operations (70h, 78h) can be used. When the LUN's status

Internal Data Move Operations
Internal Data Move Operations
Internal data move operations make it possible to transfer data within a device from
one page to another using the cache register. This is particularly useful for block management and wear leveling.
The INTERNAL DATA MOVE operation is a two-step process consisting of a READ FOR
INTERNAL DATA MOVE (00h-35h) and a PROGRAM FOR INTERNAL DATA MOVE
(85h-10h) command. To move data from one page to another on the same plane, first
issue the READ FOR INTERNAL DATA MOVE (00h-35h) command. When the die (LUN)
is ready (RDY = 1, ARDY = 1), the host can transfer the data to a new page by issuing the
PROGRAM FOR INTERNAL DATA MOVE (85h-10h) command. When the die (LUN) is
again ready (RDY = 1, ARDY = 1), the host should check the FAIL bit to verify that this
operation completed successfully.
To prevent bit errors from accumulating over multiple INTERNAL DATA MOVE operations, it is recommended that the host read the data out of the cache register after the
READ FOR INTERNAL DATA MOVE (00h-35h) completes and prior to issuing the PROGRAM FOR INTERNAL DATA MOVE (85h-10h) command. The RANDOM DATA READ
(05h-E0h) command can be used to change the column address. The host should check
the data for ECC errors and correct them. When the PROGRAM FOR INTERNAL DATA
MOVE (85h-10h) command is issued, any corrected data can be input. The PROGRAM
FOR INTERNAL DATA INPUT (85h) command can be used to change the column address.
It is not possible to use the READ FOR INTERNAL DATA MOVE operation to move data
from one plane to another or from one die (LUN) to another. Instead, use a READ PAGE
(00h-30h) or READ FOR INTERNAL DATA MOVE (00h-35h) command to read the data
out of the NAND, and then use a PROGRAM PAGE (80h-10h) command with data input
to program the data to a new plane or die (LUN).
Between the READ FOR INTERNAL DATA MOVE (00h-35h) and PROGRAM FOR INTERNAL DATA MOVE (85h-10h) commands, the following commands are supported: status
operations (70h, 78h) and column address operations (05h-E0h, 06h-E0h, 85h). The RESET operation (FFh) can be issued after READ FOR INTERNAL DATA MOVE (00h-35h),
but the contents of the cache registers on the target are not valid.
In devices that have more than one die (LUN) per target, once the READ FOR INTERNAL DATA MOVE (00h-35h) is issued, interleaved die (multi-LUN) operations are prohibited until after the PROGRAM FOR INTERNAL DATA MOVE (85h-10h) command is
issued.
Two-Plane Read for Internal Data Move Operations
Two-plane internal data move read operations improve read data throughput by copying data simultaneously from more than one plane to the specified cache registers. This
is done by issuing the READ PAGE TWO-PLANE (00h-00h-30h) command or the READ
FOR INTERNAL DATA MOVE (00h-00h-35h) command.
The INTERNAL DATA MOVE PROGRAM TWO-PLANE (85h-11h) command can be used
to further system performance of PROGRAM FOR INTERNAL DATA MOVE operations
by enabling movement of multiple pages from the cache registers to different planes of
the NAND Flash array. This is done by prepending one or more PROGRAM FOR INTERNAL DATA MOVE (85h-11h) commands in front of the PROGRAM FOR INTERNAL DATA MOVE (85h-10h) command. See Two-Plane Operations for details.

READ FOR INTERNAL DATA MOVE (00h-35h)
The READ FOR INTERNAL DATA MOVE (00h-35h) command is functionally identical to
the READ PAGE (00h-30h) command, except that 35h is written to the command register instead of 30h.
Though it is not required, it is recommended that the host read the data out of the device to verify the data prior to issuing the PROGRAM FOR INTERNAL DATA MOVE
(85h-10h) command to prevent the propagation of data errors.

Block Lock Feature
Block Lock Feature
The block lock feature protects either the entire device or ranges of blocks from being
programmed and erased. Using the block lock feature is preferable to using WP# to prevent PROGRAM and ERASE operations.
Block lock is enabled and disabled at power-on through the LOCK pin. At power-on, if
LOCK is LOW, all BLOCK LOCK commands are disabled. However if LOCK is HIGH at
power-on, the BLOCK LOCK commands are enabled and, by default, all the blocks on
the device are protected, or locked, from PROGRAM and ERASE operations, even if WP#
is HIGH.
Before the contents of the device can be modified, the device must first be unlocked.
Either a range of blocks or the entire device may be unlocked. PROGRAM and ERASE
operations complete successfully only in the block ranges that have been unlocked.
Blocks, once unlocked, can be locked again to protect them from further PROGRAM
and ERASE operations.
Blocks that are locked can be protected further, or locked tight. When locked tight, the
device’s blocks can no longer be locked or unlocked.
WP# and Block Lock
The following is true when the block lock feature is enabled:
• Holding WP# LOW locks all blocks, provided the blocks are not locked tight.
• If WP# is held LOW to lock blocks, then returned to HIGH, a new UNLOCK command
must be issued to unlock blocks.
UNLOCK (23h-24h)
By default at power-on, if LOCK is HIGH, all the blocks are locked and protected from
PROGRAM and ERASE operations. The UNLOCK (23h) command is used to unlock a
range of blocks. Unlocked blocks have no protection and can be programmed or erased.
The UNLOCK command uses two registers, a lower boundary block address register and
an upper boundary block address register, and the invert area bit to determine what
range of blocks are unlocked. When the invert area bit = 0, the range of blocks within
the lower and upper boundary address registers are unlocked. When the invert area bit
= 1, the range of blocks outside the boundaries of the lower and upper boundary address registers are unlocked. The lower boundary block address must be less than the
upper boundary block address. The figures below show examples of how the lower and
upper boundary address registers work with the invert area bit.
To unlock a range of blocks, issue the UNLOCK (23h) command followed by the appropriate address cycles that indicate the lower boundary block address. Then issue the
24h command followed by the appropriate address cycles that indicate the upper boundary block address. The least significant page address bit, PA0, should be set to 1 if setting the invert area bit; otherwise, it should be 0. The other page address bits should be
0.
Only one range of blocks can be specified in the lower and upper boundary block address registers. If after unlocking a range of blocks the UNLOCK command is again issued, the new block address range determines which blocks are unlocked. The previous
unlocked block address range is not retained.

Block Lock Feature
LOCK TIGHT (2Ch)
The LOCK TIGHT (2Ch) command prevents locked blocks from being unlocked and also prevents unlocked blocks from being locked. When this command is issued, the UNLOCK (23h) and LOCK (2Ah) commands are disabled. This provides an additional level
of protection against inadvertent PROGRAM and ERASE operations to locked blocks.
To implement LOCK TIGHT in all of the locked blocks in the device, verify that WP# is
HIGH and then issue the LOCK TIGHT (2Ch) command.
When a PROGRAM or ERASE operation is issued to a locked block that has also been
locked tight, R/B# goes LOW for tLBSY. The PROGRAM or ERASE operation does not
complete. The READ STATUS (70h) command reports bit 7 as 0, indicating that the
block is protected. PROGRAM and ERASE operations complete successfully to blocks
that were not locked at the time the LOCK TIGHT command was issued.
After the LOCK TIGHT command is issued, the command cannot be disabled via a software command. Lock tight status can be disabled only by power cycling the device or
toggling WP#. When the lock tight status is disabled, all of the blocks become locked,
the same as if the LOCK (2Ah) command had been issued.
The LOCK TIGHT (2Ch) command is disabled if LOCK is LOW at power-on.

One-Time Programmable (OTP) Operations
One-Time Programmable (OTP) Operations
This Micron NAND Flash device offers a protected, one-time programmable NAND
Flash memory area. Thirty full pages of OTP data are available on the device, and the
entire range is guaranteed to be good. The OTP area is accessible only through the OTP
commands. Customers can use the OTP area any way they choose; typical uses include
programming serial numbers or other data for permanent storage.
The OTP area leaves the factory in an unwritten state (all bits are 1s). Programming or
partial-page programming enables the user to program only 0 bits in the OTP area. The
OTP area cannot be erased, whether it is protected or not. Protecting the OTP area prevents further programming of that area.
Micron provides a unique way to program and verify data before permanently protecting it and preventing future changes. The OTP area is only accessible while in OTP operation mode. To set the device to OTP operation mode, issue the SET FEATURE (EFh)
command to feature address 90h and write 01h to P1, followed by three cycles of 00h to
P2-P4. For parameters to enter OTP mode, see Features Operations.
When the device is in OTP operation mode, all subsequent PAGE READ (00h-30h) and
PROGRAM PAGE (80h-10h) commands are applied to the OTP area. The OTP area is assigned to page addresses 02h-1Fh. To program an OTP page, issue the PROGRAM PAGE
(80h-10h) command. The pages must be programmed in the ascending order. Similarly,
to read an OTP page, issue the PAGE READ (00h-30h) command.
Protecting the OTP is done by entering OTP protect mode. To set the device to OTP protect mode, issue the SET FEATURE (EFh) command to feature address 90h and write
03h to P1, followed by three cycles of 00h to P2-P4.
To determine whether the device is busy during an OTP operation, either monitor R/B#
or use the READ STATUS (70h) command.
To exit OTP operation or protect mode, write 00h to P1 at feature address 90h.
Legacy OTP Commands
For legacy OTP commands, OTP DATA PROGRAM (A0h-10h), OTP DATA PROTECT
(A5h-10h), and OTP DATA READ (AFh-30h), refer to the MT29F4GxxAxC data sheet.

OTP DATA PROGRAM (80h-10h)
The OTP DATA PROGRAM (80h-10h) command is used to write data to the pages within
the OTP area. An OTP page allows only four partial-page programs. There is no ERASE
operation for OTP pages.
PROGRAM PAGE enables programming into an offset of an OTP page using two bytes of
the column address (CA[12:0]). The command is compatible with the RANDOM DATA
INPUT (85h) command. The PROGRAM PAGE command will not execute if the OTP
area has been protected.
To use the PROGRAM PAGE command, issue the 80h command. Issue n address cycles.
The first two address cycles are the column address. For the remaining cycles, select a
page in the range of 02h-00h through 1Fh-00h. Next, write n bytes of data. After data
input is complete, issue the 10h command. The internal control logic automatically executes the proper programming algorithm and controls the necessary timing for programming and verification.
R/B# goes LOW for the duration of the array programming time (tPROG). The READ
STATUS (70h) command is the only valid command for reading status in OTP operation
mode. Bit 5 of the status register reflects the state of R/B#. When the device is ready,
read bit 0 of the status register to determine whether the operation passed or failed (see
Status Operations). Each OTP page can be programmed to 8 partial-page programming.

OTP DATA PROTECT (80h-10)
The OTP area is protected on a block basis. To protect a block, set the device to OTP
protect mode, then issue the PROGRAM PAGE (80h-10h) command and write OTP address 00h, 00h, 00h, 00h. To set the device to OTP protect mode, issue the SET FEATURE
(EFh) command to 90h (feature address) and write 03h to P1, followed by three cycles of
00h to P2-P4.
After the data is protected, it cannot be programmed further. When the OTP area is protected, the pages within the area are no longer programmable and cannot be unprotected.
To use the PROGRAM PAGE command to protect the OTP area, issue the 80h command,
followed by n address cycles, write 00h data, data cycle of 00h, followed by the 10h command. (An example of the address sequence is shown in the following figure.) If an OTP
DATA PROGRAM command is issued after the OTP area has been protected, R/B# will
go LOW for tOBSY.
The READ STATUS (70h) command is the only valid command for reading status in OTP
operation mode. Bit 5 of the status register reflects the state of R/B#.
When the device is ready, read bit 0 of the status register to determine whether the operation passed or failed (see Status Operations).

OTP DATA READ (00h-30h)
To read data from the OTP area, set the device to OTP operation mode, then issue the
PAGE READ (00h-30h) command. Data can be read from OTP pages within the OTP area
whether the area is protected or not.
To use the PAGE READ command for reading data from the OTP area, issue the 00h
command, and then issue five address cycles: for the first two cycles, the column address; and for the remaining address cycles, select a page in the range of 02h-00h-00h
through 1Fh-00h-00h. Lastly, issue the 30h command. The PAGE READ CACHE MODE
command is not supported on OTP pages.
R/B# goes LOW (tR) while the data is moved from the OTP page to the data register. The
READ STATUS (70h) command is the only valid command for reading status in OTP operation mode. Bit 5 of the status register reflects the state of R/B# (see Status Operations).
Normal READ operation timings apply to OTP read accesses. Additional pages within
the OTP area can be selected by repeating the OTP DATA READ command.
The PAGE READ command is compatible with the RANDOM DATA OUTPUT (05h-E0h)
command.
Only data on the current page can be read. Pulsing RE# outputs data sequentially.

Two-Plane Operations
Two-Plane Operations
Each NAND Flash logical unit (LUN) is divided into multiple physical planes. Each
plane contains a cache register and a data register independent of the other planes. The
planes are addressed via the low-order block address bits. Specific details are provided
in Device and Array Organization.
Two-plane operations make better use of the NAND Flash arrays on these physical
planes by performing concurrent READ, PROGRAM, or ERASE operations on multiple
planes, significantly improving system performance. Two-plane operations must be of
the same type across the planes; for example, it is not possible to perform a PROGRAM
operation on one plane with an ERASE operation on another.
When issuing two-plane program or erase operations, use the READ STATUS (70h)
command and check whether the previous operation(s) failed. If the READ STATUS
(70h) command indicates that an error occurred (FAIL = 1 and/or FAILC = 1), use the
READ STATUS ENHANCED (78h) command to determine which plane operation failed.
Two-Plane Addressing
Two-plane commands require multiple, five-cycle addresses, one address per operational plane. For a given two-plane operation, these addresses are subject to the following requirements:
• The LUN address bit(s) must be identical for all of the issued addresses.
• The plane select bit, BA[6], must be different for each issued address.
• The page address bits, PA[5:0], must be identical for each issued address.
The READ STATUS (70h) command should be used following two-plane program page
and erase block operations on a single die (LUN).

Interleaved Die (Multi-LUN) Operations
Interleaved Die (Multi-LUN) Operations
In devices that have more than one die (LUN) per target, it is possible to improve performance by interleaving operations between the die (LUNs). An interleaved die (multiLUN) operation is one that is issued to an idle die (LUN) (RDY = 1) while another die
(LUN) is busy (RDY = 0).
Interleaved die (multi-LUN) operations are prohibited following RESET (FFh), identification (90h, ECh, EDh), and configuration (EEh, EFh) operations until ARDY =1 for all of
the die (LUNs) on the target.
During an interleaved die (multi-LUN) operation, there are two methods to determine
operation completion. The R/B# signal indicates when all of the die (LUNs) have finished their operations. R/B# remains LOW while any die (LUN) is busy. When R/B# goes
HIGH, all of the die (LUNs) are idle and the operations are complete. Alternatively, the
READ STATUS ENHANCED (78h) command can report the status of each die (LUN) individually.
If a die (LUN) is performing a cache operation, like PROGRAM PAGE CACHE (80h-15h),
then the die (LUN) is able to accept the data for another cache operation when status
register bit 6 is 1. All operations, including cache operations, are complete on a die
when status register bit 5 is 1.
During and following interleaved die (multi-LUN) operations, the READ STATUS (70h)
command is prohibited. Instead, use the READ STATUS ENHANCED (78h) command to
monitor status. This command selects which die (LUN) will report status. When twoplane commands are used with interleaved die (multi-LUN) operations, the two-plane
commands must also meet the requirements in Two-Plane Operations.
See Command Definitions for the list of commands that can be issued while other die
(LUNs) are busy.
During an interleaved die (multi-LUN) operation that involves a PROGRAM series
(80h-10h, 80h-15h) operation and a READ operation, the PROGRAM series operation
must be issued before the READ series operation. The data from the READ series operation must be output to the host before the next PROGRAM series operation is issued.
This is because the 80h command clears the cache register contents of all cache registers on all planes.

Error Management
Error Management
Each NAND Flash die (LUN) is specified to have a minimum number of valid blocks
(NVB) of the total available blocks. This means the die (LUNs) could have blocks that
are invalid when shipped from the factory. An invalid block is one that contains at least
one page that has more bad bits than can be corrected by the minimum required ECC.
Additional blocks can develop with use. However, the total number of available blocks
per die (LUN) will not fall below NVB during the endurance life of the product.
Although NAND Flash memory devices could contain bad blocks, they can be used
quite reliably in systems that provide bad block management and error-correction algorithms. This type of software environment ensures data integrity.
Internal circuitry isolates each block from other blocks, so the presence of a bad block
does not affect the operation of the rest of the NAND Flash array.
NAND Flash devices are shipped from the factory erased. The factory identifies invalid
blocks before shipping by attempting to program the bad block mark into every location in the first page of each invalid block. It may not be possible to program every location with the bad block mark. However, the first spare area location in each bad block is
guaranteed to contain the bad block mark. This method is compliant with ONFI Factory
Defect Mapping requirements. See the following table for the first spare area location
and the bad block mark.
System software should check the first spare area location on the first page of each
block prior to performing any PROGRAM or ERASE operations on the NAND Flash device. A bad block table can then be created, enabling system software to map around
these areas. Factory testing is performed under worst-case conditions. Because invalid
blocks could be marginal, it may not be possible to recover this information if the block
is erased.
Over time, some memory locations may fail to program or erase properly. In order to
ensure that data is stored properly over the life of the NAND Flash device, the following
precautions are required:
• Always check status after a PROGRAM or ERASE operation
• Under typical conditions, use the minimum required ECC (see table below)
• Use bad block management and wear-leveling algorithms
The first block (physical block address 00h) for each CE# is guaranteed to be valid
with ECC when shipped from the factory.

1. AC characteristics may need to be relaxed if I/O drive strength is not set to full.
2. Transition is measured ±200mV from steady-state voltage with load. This parameter is
sampled and not 100% tested.
3. The first time the RESET (FFh) command is issued while the device is idle, the device will
be busy for a maximum of 1ms. Thereafter, the device is busy for a maximum of 5µs.
4. Do not issue a new command during tWB, even if R/B# is ready.
