package
• Package: 240-pin very low profile dual in line
memory module (VLP DIMM)
 PCB height: 18.75mm
 Lead pitch: 1.0mm
 Lead-free (RoHS compliant)
• Power supply: VDD = 1.5V ± 0.075V
• Data rate: 1333Mbps/1066Mbps (max.)
• Eight internal banks for concurrent operation
(components)
• Interface: SSTL_15
• Burst lengths (BL): 8 and 4 with Burst Chop (BC)
• /CAS Latency (CL): 6, 7, 8, 9
• /CAS write latency (CWL): 5, 6, 7
• Precharge: auto precharge option for each burst
access
• Refresh: auto-refresh, self-refresh
• Refresh cycles
 Average refresh period
7.8µs at 0°C ≤ TC ≤ +85°C
3.9µs at +85°C < TC ≤ +95°C
• Operating case temperature range
 TC = 0°C to +95°C
• Double-data-rate architecture; two data transfers per
clock cycle
• The high-speed data transfer is realized by the 8 bits
prefetch pipelined architecture
• Bi-directional differential data strobe (DQS and /DQS)
is transmitted/received with data for capturing data at
the receiver
• DQS is edge-aligned with data for READs; centeraligned with data for WRITEs
• Differential clock inputs (CK and /CK)
• DLL aligns DQ and DQS transitions with CK
transitions
• Commands entered on each positive CK edge; data
and data mask referenced to both edges of DQS
• Posted /CAS by programmable additive latency for
better command and data bus efficiency
• On-Die-Termination (ODT) for better signal quality
 Synchronous ODT
 Dynamic ODT
 Asynchronous ODT
• Multi Purpose Register (MPR) for temperature read
out
• ZQ calibration for DQ drive and ODT
• Programmable Partial Array Self-Refresh (PASR)
• /RESET pin for Power-up sequence and reset
function
• SRT range:
 Normal/extended
 Auto/manual self-refresh
• Programmable Output driver impedance control
• 1 piece of registering clock driver and 1 piece of
serial EEPROM (256 bytes EEPROM) for Presence
Detect (PD)
• Class B temperature sensor functionality with
EEPROM
Note: Warranty void if removed DIMM heat
spreader.

Notes: 1. Stresses greater than those listed under Absolute Maximum Ratings may cause permanent damage to
the device. This is a stress rating only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect reliability.
2. Storage temperature is the case surface temperature on the center/top side of the DRAM.
3. VDD and VDDQ must be within 300mV of each other at all times; and VREF must be not greater than
0.6 × VDDQ, When VDD and VDDQ are less than 500mV; VREF may be equal to or less than 300mV.
4. DDR3 SDRAM component specification.
Caution
Exposing the device to stress above those listed in Absolute Maximum Ratings could cause
permanent damage. The device is not meant to be operated under conditions outside the limits
described in the operational section of this specification Exposure to Absolute Maximum Rating
conditions for extended periods may affect device reliability.

Notes: 1. Operating temperature is the case surface temperature on the center/top side of the DRAM.
2. The Normal Temperature Range specifies the temperatures where all DRAM specifications will be
supported. During operation, the DRAM case temperature must be maintained between 0°C to +85°C
under all operating conditions.
3. Some applications require operation of the DRAM in the Extended Temperature Range between +85°C
and +95°C case temperature. Full specifications are guaranteed in this range, but the following additional
conditions apply:
a)
Refresh commands must be doubled in frequency, therefore reducing the refresh interval tREFI to
3.9µs. (This double refresh requirement may not apply for some devices.)
b)
If Self-refresh operation is required in the Extended Temperature Range, then it is mandatory to
either use the Manual Self-Refresh mode with Extended Temperature Range capability (MR2 bit
[A6, A7] = [0, 1]) or enable the optional Auto Self-Refresh mode (MR2 bit [A6, A7] = [1, 0]).

Pin Functions
CK, /CK (input pin)
CK and /CK are differential clock inputs. All address and control input signals are sampled on the crossing of the
positive edge of CK and negative edge of /CK. Output (read) data is referenced to the crossings of CK and /CK
(both directions of crossing).
/CS (input pin)
All commands are masked when /CS is registered high. /CS provides for external rank selection on systems with
multiple ranks. /CS is considered part of the command code.
/RAS, /CAS, and /WE (input pins)
/RAS, /CAS and /WE (along with /CS) define the command being entered.
A0 to A15 (input pins)
Provided the row address for active commands and the column address for read/write commands to select one
location out of the memory array in the respective bank. (A10(AP) and A12(/BC) have additional functions, see
below) The address inputs also provide the op-code during mode register set commands.
[Address Pins Table]
Address (A0 to A13)
Row address (RA)
Column address (CA)
AX0 to AX13
AY0 to AY9, A11
Notes
A10 (AP) (input pin)
A10 is sampled during read/write commands to determine whether auto-precharge should be performed to the
accessed bank after the read/write operation. (high: auto-precharge; low: no auto-precharge)
A10 is sampled during a precharge command to determine whether the precharge applies to one bank (A10 = low)
or all banks (A10 = high). If only one bank is to be precharged, the bank is selected by bank addresses (BA).
A12 (/BC) (input pin)
A12 is sampled during read and write commands to determine if burst chop (on-the-fly) will be performed.
(A12 = high: no burst chop, A12 = low: burst chopped.)
BA0 to BA2 (input pins)
BA0, BA1 and BA2 define to which bank an active, read, write or precharge command is being applied. BA0 and
BA1 also determine if a mode register is to be accessed during a MRS cycle.

CKE (input pin)
CKE high activates, and CKE low deactivates, internal clock signals and device input buffers and output drivers.
Taking CKE low provides precharge power-down and self-refresh operation (all banks idle), or active power-down
(row active in any bank). CKE is asynchronous for self-refresh exit. After VREF has become stable during the
power-on and initialization sequence, it must be maintained for proper operation of the CKE receiver. For proper
self-refresh entry and exit, VREF must be maintained to this input. CKE must be maintained high throughout read
and write accesses. Input buffers, excluding CK, /CK, ODT and CKE are disabled during power-down. Input buffers,
excluding CKE, are disabled during self-refresh.
DQ and CB (input and output pins)
Bi-directional data bus.
DQS and /DQS (input and output pin)
Output with read data, input with write data. Edge-aligned with read data, centered in write data.
The data strobe DQS is paired with differential signals /DQS to provide differential pair signaling to the system during
READs and WRITEs.
ODT (input pins)
ODT (registered high) enables termination resistance internal to the DDR3 SDRAM. When enabled, ODT is only
applied to each DQ, DQS, /DQS, DM. The ODT pin will be ignored if the mode register (MR1) is programmed to
disable ODT.
VDD (power supply pins)
1.5V is applied. (VDD is for the internal circuit.)

CAUTION FOR HANDLING MEMORY MODULES
When handling or inserting memory modules, be sure not to touch any components on the modules, such as
the memory ICs, chip capacitors and chip resistors. It is necessary to avoid undue mechanical stress on
these components to prevent damaging them.
In particular, do not push module cover or drop the modules in order to protect from mechanical defects,
which would be electrical defects.
When re-packing memory modules, be sure the modules are not touching each other.
Modules in contact with other modules may cause excessive mechanical stress, which may damage the
modules.

NOTES FOR CMOS DEVICES
1
PRECAUTION AGAINST ESD FOR MOS DEVICES
Exposing the MOS devices to a strong electric field can cause destruction of the gate
oxide and ultimately degrade the MOS devices operation. Steps must be taken to stop
generation of static electricity as much as possible, and quickly dissipate it, when once
it has occurred. Environmental control must be adequate. When it is dry, humidifier
should be used. It is recommended to avoid using insulators that easily build static
electricity. MOS devices must be stored and transported in an anti-static container,
static shielding bag or conductive material. All test and measurement tools including
work bench and floor should be grounded. The operator should be grounded using
wrist strap. MOS devices must not be touched with bare hands. Similar precautions
need to be taken for PW boards with semiconductor MOS devices on it.
2
HANDLING OF UNUSED INPUT PINS FOR CMOS DEVICES
No connection for CMOS devices input pins can be a cause of malfunction. If no
connection is provided to the input pins, it is possible that an internal input level may be
generated due to noise, etc., hence causing malfunction. CMOS devices behave
differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed
high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected
to VDD or GND with a resistor, if it is considered to have a possibility of being an output
pin. The unused pins must be handled in accordance with the related specifications.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Power-on does not necessarily define initial status of MOS devices. Production process
of MOS does not define the initial operation status of the device. Immediately after the
power source is turned ON, the MOS devices with reset function have not yet been
initialized. Hence, power-on does not guarantee output pin levels, I/O settings or
contents of registers. MOS devices are not initialized until the reset signal is received.
Reset operation must be executed immediately after power-on for MOS devices having
reset function.
