Pin Descriptions
The pin description table below is a comprehensive list of all possible pins for all DDR3
modules. 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 ad-
dress 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 ad-
dressing 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 circui-
try 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 ac-
cess. 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) termi-
nation 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 reinitial-
ized 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 ad-
dress range on the I2C bus.
SCL Input Serial clock for temperature sensor/SPD EEPROM: Used to synchronize communi-
cation 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.

Table 7: Pin Descriptions (Continued)
Symbol Type Description
SDA I/O Serial data: Used to transfer addresses and data into and out of the temperature sen-
sor/SPD EEPROM on the I2C bus.
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
(open drain)
Parity error output: Parity error found on the command and address bus.
EVENT# Output
(open drain)
Temperature event: The EVENT# pin is asserted by the temperature sensor when crit-
ical temperature thresholds have been exceeded.
VDD Supply Power supply: 1.35V (1.283–1.45V) backward-compatible to 1.5V (1.425–1.575V). The
component VDD and VDDQ are connected to the module VDD.
VDDSPD Supply Temperature sensor/SPD EEPROM power supply: 3.0–3.6V.
VREFCA Supply Reference voltage: Control, command, and address VDD/2.
VREFDQ Supply Reference voltage: DQ, DM VDD/2.
VSS Supply Ground.
VTT Supply Termination voltage: Used for control, command, and address VDD/2.
NC No connect: These pins are not connected on the module.
NF No function: These pins are connected within the module, but provide no functional-
ity.

General Description
DDR3 SDRAM modules are high-speed, CMOS dynamic random access memory mod-
ules that use internally configured 8-bank DDR3 SDRAM devices. DDR3 SDRAM mod-
ules use DDR architecture to achieve high-speed operation. DDR3 architecture is essen-
tially 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 mod-
ule effectively consists of a single 8n-bit-wide, one-clock-cycle data transfer at the inter-
nal 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, com-
mand, and address buses have been routed in a fly-by topology, where each clock, con-
trol, command, and address pin on each DRAM is connected to a single trace and ter-
minated (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 sig-
nals can be easily accounted for by using the write-leveling feature of DDR3.
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 infor-
mation, 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 VSS, per-
manently disabling hardware write protection. For further information refer to Micron
technical note TN-04-42, "Memory Module Serial Presence-Detect."

Design Considerations
Simulations
Micron memory modules are designed to optimize signal integrity through carefully de-
signed 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 en-
sure the required supply voltage is maintained.
