6. Input/Output Functional Description
Symbol Type Function
CK0-CK1
CK0
-CK1
Input
The system clock inputs. All address and command lines are sampled on the cross point of the rising edge of CK and
falling edge of CK. A Delay Locked Loop (DLL) circuit is driven from the clock inputs and output timing for read opera-
tions is synchronized to the input clock.
CKE0-CKE1 Input
Activates the DDR3 SDRAM CK signal when high and deactivates the CK signal when low. By deactivating the clocks,
CKE low initiates the Power Down mode or the Self Refresh mode.
S
0-S1 Input
Enables the associated DDR3 SDRAM command decoder when low and disables the command decoder when high.
When the command decoder is disabled, new commands are ignored but previous operations continue. Rank 0 is
selected by S
0; Rank 1 is selected by S1.
R
AS, CAS, WE Input
When sampled at the cross point of the rising edge of CK and falling edge of CK
, signals CAS, RAS, and WE define
the operation to be executed by the SDRAM.
BA0-BA2 Input Selects which DDR3 SDRAM internal bank of eight is activated.
ODT0-ODT1 Input Asserts on-die termination for DQ, DM, DQS, and DQS signals if enabled via the DDR3 SDRAM mode register.
A0-A9,
A10/AP,
A11
A12/BC
A13-A15
Input
During a Bank Activate command cycle, defines the row address when sampled at the cross point of the rising edge of
CK and falling edge of CK
. During a Read or Write command cycle, defines the column address when sampled at the
cross point of the rising edge of CK and falling edge of CK
. In addition to the column address, AP is used to invoke
autoprecharge operation at the end of the burst read or write cycle. If AP is high, autoprecharge is selected and BA0-
BAn defines the bank to be precharged. If AP is low, autoprecharge is disabled. During a Precharge command cycle,
AP is used in conjunction with BA0-BAn to control which bank(s) to precharge. If AP is high, all banks will be pre-
charged regardless of the state of BA0-BAn inputs. If AP is low, then BA0-BAn are used to define which bank to pre-
charge.A12(BC
) is sampled during READ and WRITE commands to determine if burst chop (on-the fly) will be
performed (HIGH, no burst chop; LOW, burst chopped)
DQ0-DQ63 I/O Data Input/Output pins.
DM0-DM7 Input
The data write masks, associated with one data byte. In Write mode, DM operates as a byte mask by allowing input
data to be written if it is low but blocks the write operation if it is high. In Read mode, DM lines have no effect.
DQS0-DQS7
DQS
0-DQS7
I/O
The data strobes, associated with one data byte, sourced with data transfers. In Write mode, the data strobe is
sourced by the controller and is centered in the data window. In Read mode, the data strobe is sourced by the DDR3
SDRAMs and is sent at the leading edge of the data window. DQS
signals are complements, and timing is relative to
the crosspoint of respective DQS and DQS
.
V
DD

DDSPD,
V
SS
Supply Power supplies for core, I/O, Serial Presence Detect, Temp sensor, and ground for the module.
V
REFDQ,
V
REFCA
Supply Reference voltage for SSTL15 inputs.
SDA I/O
This is a bidirectional pin used to transfer data into or out of the SPD EEPROM and Temp sensor. A resistor must be
connected from the SDA bus line to V
DDSPD
on the system planar to act as a pull up.
SCL Input This signal is used to clock data into and out of the SPD EEPROM and Temp sensor.
SA0-SA1 Input Address pins used to select the Serial Presence Detect and Temp sensor base address.
TEST I/O The TEST pin is reserved for bus analysis tools and is not connected on normal memory modules
RESET
Input RESET In Active Low This signal resets the DDR3 SDRAM

8. Absolute Maximum Ratings
8.1 Absolute Maximum DC Ratings
NOTE :
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. For the measurement conditions, please refer to JESD51-2 standard.
3. V
DD
and V
DDQ
must be within 300mV of each other at all times;and V
REF
must be not greater than 0.6 x V
DDQ
, When V
DD
and V
DDQ
are less than 500mV; V
REF
may be
equal to or less than 300mV.
8.2 DRAM Component Operating Temperature Range
NOTE :
1. Operating Temperature T
OPER
is the case surface temperature on the center/top side of the DRAM. For measurement conditions, please refer to the JEDEC document
JESD51-2.
2. The Normal Temperature Range specifies the temperatures where all DRAM specifications will be supported. During operation, the DRAM case temperature must be main-
tained between 0-85°C under all operating conditions
3. Some applications require operation of 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 3.9us. It is also possible to specify a component with 1X refresh (tREFI
to 7.8us) in the Extended Temperature Range.
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 A6 = 0b and MR2 A7 = 1b), in this case IDD6 current can be increased around 10~20% than normal Temperature range.

V

"V

This clarifies, that dc-variations of V
REF
affect the absolute voltage a signal has to reach to achieve a valid high or low level and therefore the time to
which setup and hold is measured. System timing and voltage budgets need to account for V
REF
(DC) deviations from the optimum position within the
data-eye of the input signals.
This also clarifies that the DRAM setup/hold specification and derating values need to include time and voltage associated with V

ac-noise.
Timing and voltage effects due to ac-noise on V

up to the specified limit (+/-1% of V

) are included in DRAM timings and their associated deratings.

10.3.3 Single-ended Requirements for Differential Signals
Each individual component of a differential signal (CK, DQS, CK, DQS) has also to comply with certain requirements for single-ended signals.
CK and CK
have to approximately reach V
SEH
min / V
SEL
max (approximately equal to the ac-levels ( V
IH
(AC) / V
IL
(AC) ) for ADD/CMD signals) in every
half-cycle.
DQS, DQS
have to reach V
SEH
min / V
SEL
max (approximately the ac-levels ( V
IH
(AC) / V
IL
(AC) ) for DQ signals) in every half-cycle proceeding and follow-
ing a valid transition.
Note that the applicable ac-levels for ADD/CMD and DQ’s might be different per speed-bin etc. E.g. if V
IH
150(AC)/V
IL
150(AC) is used for ADD/CMD
signals, then these ac-levels apply also for the single-ended signals CK and CK
.
Figure 3. Single-ended requirement for differential signals
Note that while ADD/CMD and DQ signal requirements are with respect to V
REF
, the single-ended components of differential signals have a requirement
with respect to V
DD
/2; this is nominally the same. The transition of single-ended signals through the ac-levels is used to measure setup time. For single-
ended components of differential signals the requirement to reach V
SEL
max, V
SEH
min has no bearing on timing, but adds a restriction on the common
mode characteristics of these signals.

Unbuffered SODIMM datasheet DDR3 SDRAM
Rev. 1.0
NOTE :
1) Burst Length: BL8 fixed by MRS: set MR0 A[1,0]=00B
2) Output Buffer Enable: set MR1 A[12] = 0B; set MR1 A[5,1] = 01B; RTT_Nom enable: set MR1 A[9,6,2] = 011B; RTT_Wr enable: set MR2 A[10,9] = 10B
3) Precharge Power Down Mode: set MR0 A12=0B for Slow Exit or MR0 A12=1B for Fast Exit
4) Auto Self-Refresh (ASR): set MR2 A6 = 0B to disable or 1B to enable feature
5) Self-Refresh Temperature Range (SRT): set MR2 A7=0B for normal or 1B for extended temperature range
6) Refer to DRAM supplier data sheet and/or DIMM SPD to determine if optional features or requirements are supported by DDR3 SDRAM device
7) IDD current measure method and detail patterns are described on DDR3 component datasheet
8) VDD and VDDQ are merged on module PCB.
9) DIMM IDD SPEC is measured with Qoff condition
(IDDQ values are not considered)
