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, or MR3) is loaded during the LOAD MODE command. CKx, CKx# 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 DRAM. 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 DDR3 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 (LVCMOS) Reset: RESET# is an active LOW asychronous input that is connected to each DRAM and the registering clock driver. After RESET# goes HIGH, the DRAM must be reinitialized as though a normal power-up was executed. Sx# Input Chip select: Enables (registered LOW) and disables (registered HIGH) the command decoder. SAx Input Serial address inputs: Used to configure the temperature sensor/SPD EEPROM address range on the I2C bus. SCL Input Serial clock for temperature sensor/SPD EEPROM: Used to synchronize communication to and from the temperature sensor/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, DQSx# I/O Data strobe: Differential data strobes. Output with read data; edge-aligned with read data; input with write data; center-aligned with write data. PDF: 09005aef8360c8e6 jsf9c128_256x72az.pdf - Rev.

TDQSx, TDQSx# Output Redundant data strobe (x8 devices only): TDQS is enabled/disabled via the LOAD MODE command to the extended mode register (EMR). When TDQS is enabled, DM is disabled and TDQS and TDQS# provide termination resistance; otherwise, TDQS# are no function. Err_Out# Output Parity error output: Parity error found on the command and address bus. (open drain) EVENT# Output Temperature event: The EVENT# pin is asserted by the temperature sensor when crit(open drain) ical temperature thresholds have been exceeded.

All rights reserved. 1GB, 2GB (x72, ECC, SR) 240-Pin DDR3 UDIMM General Description General Description DDR3 SDRAM modules are high-speed, CMOS dynamic random access memory modules that use internally configured 8-bank DDR3 SDRAM devices. DDR3 SDRAM modules use DDR architecture to achieve high-speed operation. DDR3 architecture is essentially an 8n-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 DDR3 SDRAM module effectively consists of a single 8n-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. DDR3 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. Fly-By Topology DDR3 modules use faster clock speeds than earlier DDR technologies, making signal quality more important than ever. For improved signal quality, the clock, control, command, and address buses have been routed in a fly-by topology, where each clock, control, command, and address pin on each DRAM is connected to a single trace and terminated (rather than a tree structure, where the termination is off the module near the connector). Inherent to fly-by topology, the timing skew between the clock and DQS signals can be easily accounted for by using the write-leveling feature of DDR3. Temperature Sensor with Serial Presence-Detect EEPROM Thermal Sensor Operations The temperature from the integrated thermal sensor is monitored and converts into a digital word via the I2C bus. System designers can use the user-programmable registers to create a custom temperature-sensing solution based on system requirements. Programming and configuration details comply with JEDEC standard No. 21-C page 4.7-1, "Definition of the TSE2002av, Serial Presence Detect with Temperature Sensor." Serial Presence-Detect EEPROM Operation DDR3 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 comply with JEDEC standard JC-45, "Appendix X: Serial Presence Detect (SPD) for DDR3 SDRAM Modules." These bytes identify module-specific timing parameters, configuration information, and physical attributes. 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. For further information refer to Micron technical note TN-04-42, "Memory Module Serial Presence-Detect."

Table 10: Module and Component Speed Grades DDR3 components may exceed the listed module speed grades; module may not be available in all listed speed grades Module Speed Grade Component Speed Grade -2G1 -093 -1G9 -107 -1G6 -125 -1G4 -15E -1G1 -187E -1G0 -187 -80C -25E -80B -25 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. PDF: 09005aef8360c8e6 jsf9c128_256x72az.pdf - Rev.

All rights reserved. 1GB, 2GB (x72, ECC, SR) 240-Pin DDR3 UDIMM Temperature Sensor with Serial Presence-Detect EEPROM EVENT# Pin The temperature sensor also adds the EVENT# pin (open-drain). Not used by the SPD EEPROM, EVENT# is a temperature sensor output used to flag critical events that can be set up in the sensor’s configuration register. EVENT# has three defined modes of operation: interrupt mode, compare mode, and critical temperature mode. Event thresholds are programmed in the 0x01 register using a hysteresis. The alarm window provides a comparison window, with upper and lower limits set in the alarm upper boundary register and the alarm lower boundary register, respectively. When the alarm window is enabled, EVENT# will trigger whenever the temperature is outside the MIN or MAX values set by the user. The interrupt mode enables software to reset EVENT# after a critical temperature threshold has been detected. Threshold points are set in the configuration register by the user. This mode triggers the critical temperature limit and both the MIN and MAX of the temperature window. The compare mode is similar to the interrupt mode, except EVENT# cannot be reset by the user and returns to the logic HIGH state only when the temperature falls below the programmed thresholds. Critical temperature mode triggers EVENT# only when the temperature has exceeded the programmed critical trip point. When the critical trip point has been reached, the temperature sensor goes into comparator mode, and the critical EVENT# cannot be cleared through software.
