Pin Descriptions
Pin Descriptions
The pin description table below is a comprehensive list of all possible pins for all DDR2
modules. All pins listed may not be supported on this module. See Pin Assignments for
information specific to this module.
Table 6: Pin Descriptions
Symbol
Type
Description
Ax
Input
Address inputs: Provide the row address for ACTIVE commands, and the column address and auto precharge bit (A10) for READ/WRITE commands, to select one location
out of the memory array in the respective bank. A10 sampled during a PRECHARGE
command determines whether the PRECHARGE applies to one bank (A10 LOW, bank
selected by BAx) or all banks (A10 HIGH). The address inputs also provide the op-code
during a LOAD MODE command. See the Pin Assignments Table for density-specific
addressing information.
BAx
Input
Bank address inputs: Define the device bank to which an ACTIVE, READ, WRITE, or
PRECHARGE command is being applied. BA define which mode register (MR0, MR1,
MR2, and MR3) is loaded during the LOAD MODE command.
CKx,
CK#x
Input
Clock: Differential clock inputs. All control, command, and address input signals are
sampled on the crossing of the positive edge of CK and the negative edge of CK#.
CKEx
Input
Clock enable: Enables (registered HIGH) and disables (registered LOW) internal circuitry and clocks on the DDR2 SDRAM.
DMx
Input
Data mask (x8 devices only): DM is an input mask signal for write data. Input data
is masked when DM is sampled HIGH, along with that input data, during a write access. Although DM pins are input-only, DM loading is designed to match that of the
DQ and DQS pins.
ODTx
Input
On-die termination: Enables (registered HIGH) and disables (registered LOW) termination resistance internal to the DDR2 SDRAM. When enabled in normal operation,
ODT is only applied to the following pins: DQ, DQS, DQS#, DM, and CB. The ODT input
will be ignored if disabled via the LOAD MODE command.
Par_In
Input
Parity input: Parity bit for Ax, RAS#, CAS#, and WE#.
RAS#, CAS#, WE#
Input
Command inputs: RAS#, CAS#, and WE# (along with S#) define the command being
entered.
RESET#
Input
Reset: Asynchronously forces all registered outputs LOW when RESET# is LOW. This
signal can be used during power-up to ensure that CKE is LOW and DQ are High-Z.
S#x
Input
Chip select: Enables (registered LOW) and disables (registered HIGH) the command
decoder.
SAx
Input
Serial address inputs: Used to configure the SPD EEPROM address range on the I2C
bus.
SCL
Input
Serial clock for SPD EEPROM: Used to synchronize communication to and from the
SPD EEPROM on the I2C bus.
CBx
I/O
Check bits. Used for system error detection and correction.
DQx
I/O
Data input/output: Bidirectional data bus.
DQSx,
DQS#x
I/O
Data strobe: Travels with the DQ and is used to capture DQ at the DRAM or the controller. Output with read data; input with write data for source synchronous operation. DQS# is only used when differential data strobe mode is enabled via the LOAD
MODE command.

I/O
Serial data: Used to transfer addresses and data into and out of the SPD EEPROM on
the I2C bus.
RDQSx,
RDQS#x
Output
Redundant data strobe (x8 devices only): RDQS is enabled/disabled via the LOAD
MODE command to the extended mode register (EMR). When RDQS is enabled, RDQS
is output with read data only and is ignored during write data. When RDQS is disabled, RDQS becomes data mask (see DMx). RDQS# is only used when RDQS is enabled
and differential data strobe mode is enabled.

General Description
General Description
DDR2 SDRAM modules are high-speed, CMOS dynamic random access memory modules that use internally configured 4 or 8-bank DDR2 SDRAM devices. DDR2 SDRAM
modules use DDR architecture to achieve high-speed operation. DDR2 architecture is
essentially a 4n-prefetch architecture with an interface designed to transfer two data
words per clock cycle at the I/O pins. A single read or write access for the DDR2 SDRAM
module effectively consists of a single 4n-bit-wide, one-clock-cycle data transfer at the
internal DRAM core and eight corresponding n-bit-wide, one-half-clock-cycle data
transfers at the I/O pins.
DDR2 modules use two sets of differential signals: DQS, DQS# to capture data and CK
and CK# to capture commands, addresses, and control signals. Differential clocks and
data strobes ensure exceptional noise immunity for these signals and provide precise
crossing points to capture input signals. A bidirectional data strobe (DQS, DQS#) is
transmitted externally, along with data, for use in data capture at the receiver. DQS is a
strobe transmitted by the DDR2 SDRAM device during READs and by the memory controller during WRITEs. DQS is edge-aligned with data for READs and center-aligned
with data for WRITEs.
DDR2 SDRAM modules operate from a differential clock (CK and CK#); the crossing of
CK going HIGH and CK# going LOW will be referred to as the positive edge of CK. Commands (address and control signals) are registered at every positive edge of CK. Input
data is registered on both edges of DQS, and output data is referenced to both edges of
DQS, as well as to both edges of CK.
Serial Presence-Detect EEPROM Operation
DDR2 SDRAM modules incorporate serial presence-detect. The SPD data is stored in a
256-byte EEPROM. The first 128 bytes are programmed by Micron to identify the module type and various SDRAM organizations and timing parameters. The remaining 128
bytes of storage are available for use by the customer. System READ/WRITE operations
between the master (system logic) and the slave EEPROM device occur via a standard
I2C bus using the DIMM’s SCL (clock) SDA (data), and SA (address) pins. Write protect
(WP) is connected to V SS, permanently disabling hardware write protection.
Register and PLL Operation
DDR2 SDRAM modules operate in registered mode, where the command/address input
signals are latched in the registers on the rising clock edge and sent to the DDR2
SDRAM devices on the following rising clock edge (data access is delayed by one clock
cycle). A phase-lock loop (PLL) on the module receives and redrives the differential
clock signals (CK, CK#) to the DDR2 SDRAM devices. The registers and PLL minimize
system and clock loading. PLL clock timing is defined by JEDEC specifications and ensured by use of the JEDEC clock reference board. Registered mode will add one clock
cycle to CL.
Parity Operations
The registering clock driver can accept a parity bit from the system’s memory controller, providing even parity for the control, command, and address bus. Parity errors are
flagged on the Err_Out# pin. Systems not using parity are expected to function without
issue if Par_In and Err_Out# are left as no connects (NC) to the system.

Design Considerations
Simulations
Micron memory modules are designed to optimize signal integrity through carefully designed terminations, controlled board impedances, routing topologies, trace length
matching, and decoupling. However, good signal integrity starts at the system level. Micron encourages designers to simulate the signal characteristics of the system's memory bus to ensure adequate signal integrity of the entire memory system.
Power
Operating voltages are specified at the DRAM, not at the edge connector of the module.
Designers must account for any system voltage drops at anticipated power levels to ensure the required supply voltage is maintained.

1. To avoid spurious start and stop conditions, a minimum delay is placed between SCL = 1
and the falling or rising edge of SDA.
2. This parameter is sampled.
3. For a restart condition or following a WRITE cycle.
4. The SPD EEPROM WRITE cycle time (tWRC) is the time from a valid stop condition of a
write sequence to the end of the EEPROM internal ERASE/PROGRAM cycle. During the
WRITE cycle, the EEPROM bus interface circuit is disabled, SDA remains HIGH due to
pull-up resistance, and the EEPROM does not respond to its slave address.
