A10 sampled during a PRECHARGE command determines whether the PRECHARGE applies to one device bank (A10 LOW, device bank selected by BA[2:0]) or all device banks (A10 HIGH). The address inputs also provide the opcode during a LOAD MODE command. A[13:0] 2GB. A[15:14] are connected for parity. Bank address inputs: BA[2:0] define the device bank to which an ACTIVE, READ, WRITE, or PRECHARGE command is being applied. BA[2:0] define which mode register (MR, EMR1, EMR2, and EMR3) is loaded during the LOAD MODE command. Clock: CK and CK# are 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#. Clock enable: CKE enables (registered HIGH) and disables (registered LOW) internal circuitry and clocks on the DDR2 SDRAM. Input data mask: DM is an input mask signal for write data. Input data is masked when DM is sampled HIGH, along with the input data, during a write access. DM is sampled on both edges of DQS. Although the DM pins are input-only, DM loading is designed to match that of the DQ and DQS pins. If RDQS is disabled, RDQS[8:0] become DM[8:0] and RDQS#[8:0] are no function. On-die termination: ODT 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. Parity input: Parity bit for the address, RAS#, CAS#, and WE#. Command inputs: RAS#, CAS#, and WE# (along with S#) define the command being entered. 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. Chip select: S# enables (registered LOW) and disables (registered HIGH) the command decoder. Serial address inputs: These pins are used to configure the SPD EEPROM address range on the I2C bus. Serial clock for SPD EEPROM: SCL is used to synchronize communication to and from the SPD EEPROM. Check bits. Data input/output: Bidirectional data bus. Data strobe: Output with read data. Edge-aligned with read data. Input with write data. Center-aligned with write data. DQS# is only used when differential data strobe mode is enabled via the LOAD MODE command. Serial data: SDA is a bidirectional pin used to transfer addresses and data into and out of the SPD EEPROM on the module on the I2C bus. Parity error output: Parity error found on the command and address bus. Output (open drain) Supply Power supply: 1.8V ±0.1V. The component VDD and VDDQ are connected to the module VDD. Supply SPD EEPROM power supply: +1.7V to +3.6V. Supply Reference voltage: VDD/2. Supply Ground. – No connect: These pins are not connected on the module.

All rights reserved. 2GB (x72, DR) 244-Pin DDR2 Mini-RDIMM General Description General Description The MT18HTF25672PK(I)Z DDR2 SDRAM module is a high-speed, CMOS, dynamic random-access 2GB memory module, organized in x72 configuration. This DDR2 SDRAM module uses internally configured eight-bank 1Gb DDR2 SDRAM devices. DDR2 SDRAM modules use double data rate architecture to achieve high-speed operation. The double data rate 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-bitwide, one-clock-cycle data transfer at the internal DRAM core and four corresponding n-bit-wide, one-half-clock-cycle data transfers at the I/O pins. 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 edgealigned with data for READs and center-aligned with data for WRITEs. These 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. Register and PLL EEPROM 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 register(s) and PLL reduce clock, control, command, and address signals loading by isolating DRAM from the system controller. 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 to the system. 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) and SDA (data) signals, together with SA[2:0], which provide eight unique DIMM/EEPROM addresses. Write protect (WP) is connected to VSS, permanently disabling hardware write protection. PDF: 09005aef83d235f2/Source: 09005aef83d23625 HTF18C256x72PKZ.fm - 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.

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 pullup resistance, and the EEPROM does not respond to its slave address.
