The ALE controls the address input. When the ALE goes high, the address is latched at the rising edge of WE#. I/O PORT: IOx - IO0 WRITE PROTECT: WP# The IOx to IO0 pins are for address/command input and data output to/from the device. IO7-IO0 pins are for x8 device, IO15-IO0 pins are for x16 device. The WP# signal keeps low and then the memory will not accept the program/erase operation. It is recommended to keep WP# pin low during power on/off sequence. Please refer to the waveform of "Power On/Off Sequence". CHIP ENABLE: CE# The device goes into low-power Standby Mode when CE# goes high during a read operation and not at busy stage. READY/Busy: R/B# The R/B# is an open-drain output pin. The R/B# outputs the ready/busy status of read/program/ erase operation of the device. When the R/B# is at low, the device is busy for read or program or erase operation. When the R/B# is at high, the read/ program/erase operation is finished. The CE# goes low to enable the device to be ready for standard operation. When the CE# goes high, the device is deselected. However, when the device is at busy stage, the device will not go to standby mode when CE# pin goes high. Please refer to Section 9-1 for details. READ ENABLE: RE# PROTECTION: PT The RE# (Read Enable) allows the data to be output by a tREA time after the falling edge of RE#. The internal address counter is automatically increased by one at the falling edge of RE#. The PT pin is the hardware method to protect the whole chip from program/erase operation. When the PT pin is at high at power-on, the whole chip is protected even the WP# is at high; the un-protect command and procedure is necessary before any program/erase operation. When the PT pin is connected to low or floating, the Protection function is disabled. WRITE ENABLE: WE# When the WE# goes low, the address/data/ command are latched at the rising edge of WE#. Please refer to Section - Block Protection for details. COMMAND LATCH ENABLE: CLE The CLE controls the command input. When the CLE goes high, the command data is latched at the rising edge of the WE#.

Page Read The MX30UFxG26(28)AB array is accessed in Page of 2160 bytes or 1,080 words. External reads begins after the R/B# pin goes to READY. The Read operation may also be initiated by writing the 00h command and giving the address (column and row address) and being confirmed by the 30h command, the device begins the internal read operation and the chip enters busy state. The data can be read out in sequence after the chip is ready. Refer to the waveform for Read Operation as below. If the host side uses a sequential access time (tRC) of less than 30ns, the data can be latched on the next falling edge of RE# as the waveform of EDO mode (Figure 9-2).

Cache Read Sequential The cache read sequential operation is for throughput enhancement by using the internal cache buffer. It allows the consecutive pages to be read-out without giving next page address, which reduces the latency time from tR to tRCBSY between pages or blocks. While the data is read out on one page, the data of next page can be read into the cache buffer. After writing the 00h command, the column and row address should be given for the start page selection, and followed by the 30h command for address confirmation. After that, the CACHE READ operation starts after a latency time tR and following a 31h command with the latency time of tRCBSY, the data can be readout sequentially from 1st column address (A[11:0]=00h) without giving next page address input. The 31h command is necessary to confirm the next cache read sequential operation and followed by a tRCBSY latency time before next page data is necessary. The CACHE READ SEQUENTIAL command is also valid for the consecutive page cross block. The random data out (05h-E0h) command set is available to change the column address of the current page data in the cache register. The user can check the chip status by the following method: - R/B# pin ("0" means the data is not ready, "1" means the user can read the data) - Status Register (SR[6] functions the same as R/B# pin, SR[5] indicates the internal chip operation, "0" means the chip is in internal operation and "1" means the chip is idle.) Status Register can be checked after the Read Status command (70h) is issued. Command 00h should be given to return to the cache read sequential operation. To confirm the last page to be read-out during the cache read sequential operation, a 3Fh command is needed to replace the 31h command prior to the last data-out.

Cache Read Random The main difference from the Cache Read Sequential operation is the Cache Read Random operation may allow the random page to be read-out with cache operation not just for the consecutive page only. After writing the 00h command, the column and row address should be given for the start page selection, and followed by the 30h command for address confirmation. The column address is ignored in the cache read random operation. And then, the CACHE READ RANDOM operation starts after a latency time tR and following a 00h command with the selected page address and following a 31h command, the data can be read-out after the latency time of tRCBSY. After the previous selected page data out, a new selected page address can be given by writing the 00h-31h command set again. The CACHE READ RANDOM command is also valid for the consecutive page cross block. The random data out (05h-E0h) command set is available to change the column address of the current page data in the cache register. The user can check the chip status by the following method: - R/B# pin ("0" means the data is not ready, "1" means the user can read the data) - Status Register can be checked after the Read Status command (70h) is issued. (SR[6] behaves the same as R/B# pin, SR[5] indicates the internal chip operation, "0" means the chip is in internal operation and "1" means the chip is idle.) Command 00h should be given to return to the cache read operation. To confirm the last page to be read-out during the cache read operation, a 3Fh command is needed to replace the 31h command prior to the last data-out.

Page Program The memory is programmed by page, which is 2,160 bytes, or 1080 words. After Program load command (80h) is issued and the row and column address is given, the data will be loaded into the chip sequentially. Random Data Input command (85h) allows multi-data load in non-sequential address. After data load is complete, program confirm command (10h) is issued to start the page program operation. The page program operation in a block should start from the low address to high address. Partial program in a page is allowed up to 4 times. However, the random data input mode for programming a page is allowed and number of times is not limited. The status of the program completion can be detected by R/B# pin or Status register bit SR[6]. The program result is shown in the chip status bit (SR[0]). SR[0] = 1 indicates the Page Program is not successful and SR[0] = 0 means the program operation is successful. During the Page Program progressing, only the read status register command and reset command are accepted, others are ignored. Figure 12.

Cache Program The cache program feature enhances the program performance by using the cache buffer of 2,160-byte or 1080 words. The serial data can be input to the cache buffer while the previous data stored in the buffer are programming into the memory cell. Cache Program command sequence is almost the same as page program command sequence. Only the Program Confirm command (10h) is replaced by cache Program command (15h). After the Cache Program command (15h) is issued. The user can check the status by the following methods. - R/B# pin - Cache Status Bit (SR[6] = 0 indicates the cache is busy; SR[6] = 1 means the cache is ready). The user can issue another Cache Program Command Sequence after the Cache is ready. The user can always monitor the chip state by Ready/Busy Status Bit (SR[5]). The user can issues either program confirm command (10h) or cache program command (15h) for the last page if the user monitor the chip status by issuing Read Status Command (70h). However, if the user only monitors the R/B# pin, the user needs to issue the program confirm command (10h) for the last page. The user can check the Pass/Fail Status through P/F Status Bit (SR[0]) and Cache P/F Status Bit (SR[1]). SR[1] represents Pass/Fail Status of the previous page. SR[1] is updated when SR[6] change from 0 to 1 or Chip is ready. SR[0] shows the Pass/Fail status of the current page. It is updated when SR[5] change from "0" to "1" or the end of the internal programming. For more details, please refer to the related waveforms.

ID Read The device contains ID codes that identify the device type and the manufacturer. The ID READ command sequence includes one command Byte (90h), one address byte (00h). The Read ID command 90h may provide the manufacturer ID (C2h) of one-byte and device ID (AAh for 2Gb, x8; BAh for 2Gb, X16; ACh for 4Gb, X8; BCh for 4Gb, X16) of one-byte, also Byte2, Byte3, and Byte4 ID code are followed. The device support ONFI Parameter Page Read, by sending the ID Read (90h) command and following one byte address (20h), the four-byte data returns the value of 4Fh-4Eh-46h-49h for the ASCII code of "O"-"N""F"-"I" to identify the ONFI parameter page.

Status Read The MX30UFxG26(28)AB provides a status register that outputs the device status by writing a command code 70h, and then the IO pins output the status at the falling edge of CE# or RE# which occurs last. Even though when multiple flash devices are connecting in system and the R/B#pins are common-wired, the two lines of CE# and RE# may be checked for individual devices status separately. The status read command 70h will keep the device at the status read mode unless next valid command is issued. The resulting information is outlined in Table 4 as below. Table 4.

Please refer to ONFI 1.0 specifications for details. The CRC shall be calculated using the following 16-bit generator polynomial: G(X) = X16 + X15 +X2 + 1 6-13. Unique ID Read (ONFI) The unique ID is 32-byte and with 16 copies for back-up purpose. After writing the Unique ID read command (EDh) and following the one address byte (00h), the host may read out the unique ID data. The host need to XOR the 1st 16-byte unique data and the 2nd 16-byte complement data to get the result, if the result is FFh, the unique ID data is correct; otherwise, host need to repeat the XOR with the next copy of Unique ID data. Once sending the EDh command, the NAND device will remain in the Unique ID read mode until next valid command is sent. To change the data output location, it is recommended to use the Random Data Out command set (05h-E0h). The Status Read command (70h) can be used to check the completion. To continue the read operation, a following read command (00h) to re-enable the data out is necessary. P/N: PM2031 REV. 1.0, MAY 29, 2014 46 MX30UF2G26(28)AB MX30UF4G26(28)AB Figure 24.

Secure OTP (One-Time-Programmable) Feature There is an OTP area which has thirty full pages (30 x 2,160-byte) guarantee to be good for system device serial number storage or other fixed code storage. The OTP area is a non-erasable and one-timeprogrammable area, which is default to “1” and allows whole page or partial page program to be “0”, once the OTP protection mode is set, the OTP area becomes read-only and cannot be programmed again. The OTP operation is operated by the Set Feature/ Get Feature operation to access the OTP operation mode and OTP protection mode. To check the NAND device is ready or busy in the OTP operation mode, either checking the R/B# or writing the Status Read command (70h) may collect the status. To exit the OTP operation or protect mode, it can be done by writing 00h to P1 at feature address 90h. OTP Read/Program Operation To enter the OTP operation mode, it is by using the Set Feature command (EFh) and followed by the feature address (90h) and then input the 01h to P1 and 00h to P2-P4 of sub-Feature Parameter data( please refer to the sub-Feature Parameter table). After enter the OTP operation mode, the normal Read command (00h-30h) or Page program( 80h-10h) command can be used to read the OTP area or program it. The address of OTP is located on the 02h-1Fh of page address. Besides the normal Read command, the Random Data Output command (05h-E0h) can be used for read OTP data. However, the Cache Read command is not supported in the OTP area. Besides the normal page program command, the Random Data Input command (85h) allows multi-data load in non-sequential address. After data load is completed, a program confirm command (10h) is issued to start the page program operation. The number of partial-page OTP program is 8 per each OTP page. Figure 28.

In the two-plane operation, the NAND device may proceed the same type operation (for example: Program or Erase) on the two planes concurrent or overlapped by the two-plane command sets. The different type operations cannot be done in the two-plane operations; for example, it cannot be done to erase one plane and program the other plane concurrently. The plane address A18 (for x8 bus) or A17 (for x16 bus) must be different from each selected plane address. The page address A12-A17(for x8 bus) or A11-A16 (for x16 bus) of individual plane must be the same for twoplane operation. The Status Read command( 70h) may check the device status in the two-plane operation, if the result is failed and then the Status Enhanced Read (78h) may check which plane is failed.

Two-plane Program (ONFI) and Two-plane Cache Program (ONFI) The two-plane program command (80h-11h) may input data to cache buffer and wait for the final plane data input with command (80h-10h) and then transfer all data to NAND array. As for the two-plane cache program operation, after the prior two-plane program command (80h-11h) is the cache program command (80h-15h) for the overhead time reduction. Please refer to the waveforms of two-plane program and two-plane cache program for details. The random data input command (85h) can be also used in the two-plane program operation for changing the column address, please refer to the waveform of two-plane program with random data input.

Block Protection The block protect operation can protect the whole chip or selected blocks from erasing or programming. Through the PT pin at power-on stage, it decides the block protect command is enabled or disabled. At power-on, if the PT pin is connected to high, the related Block Protect command sets are enabled; in contrast, if the PT pin is low, all the block protect command sets are disabled. If the PT pin is connected to high at power-on, all the blocks are default to be protected from programming/erasing even the WP# is disabled, the block un-protect command is necessary to un-protect those selected blocks before those selected blocks to be updated. Once the selected blocks are un-protected, those blocks can be protected again. Besides the Block protect operation, there is “Block Solid-Protect” command (2Ch) may provide a solid block protection; once the block is solid-protected, the block is protected from programming or erasing and cannot be upprotected until next power cycle. 6-18-1. Block Un-Protect When PT pin is connected to high at the power-on stage, all blocks are default to be protected from programming or erasing. The Block Un-Protect command set (23h-24h) may define the range of blocks to be un-protected. The Block Un-Protect Lower command (23h) may set the lower boundary address and followed by the Block Un-Protect Upper command (24h) setting the upper boundary address and the invert-bit to define the un-protect blocks range. The invert-bit defines the un-Protect block area, if the invert-bit is set to “0” which sets the un-Protected area is within the upper and lower boundary address; in contrast, the bit is set to “1” which means the un-protected area is outside the upper and lower boundary address.

Block Solid-Protect The Block Solid-Protect Command (2Ch) may firmly maintain the previous block protect status; which means the protected blocks cannot be un-protected and the un-protected blocks cannot be protected. Once the Block Solid-Protect command is set, only a new power cycle may change the states of blocks protection/unprotection. The WP# needs to be connected to high before writing the Block Solid-Protect command, and the command is valid only when the PT pin is connected to high. The Block Solid-Protect command was issued, only the un-protected blocks may accept the program/erase operation. To program or erase the protected block, the R/B# keeps low for the time of tLPSY, and the Status Read command (70h) may get the 60h result. Figure 39.

R/B#: Termination for The Ready/Busy# Pin (R/B#) The R/B# is an open-drain output pin and a pull-up resistor is necessary to add on the R/B# pin. The R/B# outputs the ready/busy status of read/program/ erase operation of the device. When the R/B# is at low, the device is busy for read or program or erase operation. When the R/B# is at high, the read/program/erase operation is finished. Rp Value Guidence The rise time of the R/B# signal depends on the combination of Rp and capacitive loading of the R/B# circuit. It is approximately two times constants (Tc) between the 10% and 90% points on the R/B# waveform. TC = R × C Where R = Rp (Resistance of pull-up resistor), and C = CL (Total capacitive load) The fall time of the R/B# signal majorly depends on the output impedance of the R/B# signal and the total load capacitance. Rp (Min.) = Vcc (Max.) - VOL (Max.) IOL+ΣIL Notes: 1. Considering of the variation of device-by-device, the above data is for reference to decide the resistor value. 2. Rp maximum value depends on the maximum permissible limit of tr. 3. IL is the total sum of the input currents of all devices tied to the R/B pin.

Power On/Off Sequence After the Chip reaches the power on level (Vth = Vcc min.), the internal power on reset sequence will be triggered. During the internal power on reset period, no any external command is accepted. There are two ways to identify the termination of the internal power on reset sequence. Please refer to Figure 48.

Invalid Blocks (Bad Blocks) The bad blocks are included in the device while it gets shipped. During the time of using the device, the additional bad blocks might be increasing; therefore, it is recommended to check the bad block marks and avoid using the bad blocks. Furthermore, please read out the bad block information before any erase operation since it may be cleared by any erase operation. Figure 44. Bad Blocks Bad Block Bad Block While the device is shipped, the value of all data bytes of the good blocks are FFh. The 1st byte of the 1st or 2nd page in the spare area for bad block will not be FFh for x8; and not be FFFFh for x16 (either first or second byte is not FFh). The erase operation at the bad blocks is not recommended. After the device is installed in the system, the bad block checking is recommended. The figure shows the brief test flow by the system software managing the bad blocks while the bad blocks were found. When a block gets damaged, it should not be used any more. Due to the blocks are isolated from bit-line by the selected gate, the performance of good blocks will not be impacted by bad ones. Table 17.

REV. 1.0, MAY 29, 2014 78 MX30UF2G26(28)AB MX30UF4G26(28)AB 9-2. Bad Block Test Flow Although the initial bad blocks are marked by the flash vendor, they could be inadvertently erased and destroyed by a user that does not pay attention to them. To prevent this from occurring, it is necessary to always know where any bad blocks are located. Continually checking for bad block markers during normal use would be very time consuming, so it is highly recommended to initially locate all bad blocks and build a bad block table and reference it during normal NAND flash use. This will prevent having the initial bad block markers erased by an unexpected program or erase operation. Failure to keep track of bad blocks can be fatal for the application. For example, if boot code is programmed into a bad block, a boot up failure may occur. The following section shows the recommended flow for creating a bad block table. Figure 45. Bad Block Test Flow Start Block No. = 0 Fail (Note) Read FFh Check Create (or Update) Bad Block Pass Block No. = 4095 Block No. = Block No. + 1 (Note1) No Yes End Note 1. The block No. = 2047 for 2Gb, 4095 for 4Gb 9-3. Failure Phenomena for Read/Program/Erase Operations The device may fail during a Read, Program or Erase operation.
