All pins listed may not be supported on this module. See Pin Assignments for information specific to this module. Table 7: 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.

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. Err_Out# Description Output Parity error output: Parity error found on the command and address bus.

All rights reserved. 1GB, 2GB, 4GB (x64, DR) 200-Pin DDR2 SDRAM SODIMM 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. PDF: 09005aef8339ef97 htf16c128_256_512x64hz.pdf - Rev.

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. PDF: 09005aef8339ef97 htf16c128_256_512x64hz.pdf - Rev.

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. 16 Micron Technology, Inc. reserves the right to change products or specifications without notice. © 2008 Micron Technology, Inc.
