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 input and output timing for read operations is synchronized to the input clock.
CKE0-CKE1
Input
Activates the DDR2 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 Refesh mode.
S0-S1
Input
Enables the associated DDR2 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 S0,
Rank 1 is selected by S1. Ranks are also called “Physical banks”.
RAS, CAS, WE
Input
When sampled at the cross point of the rising edge of CK and falling edge of CK, CAS, RAS, and WE define the operation
to be executed by the SDRAM.
BA0~BA1
Input
Selects which DDR2 SDRAM internal bank is activated.
ODT0~ODT1
Input
Asserts on-die termination for DQ, DM, DQS, and DQS signals if enabled via the DDR2 SDRAM Extended Mode Register
Set (EMRS).
A0~A9,
A10/AP,
A11~A13
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 pecharged regardiess of the state of
BA0-BAn inputs. If AP is low, then BA0-BAn are used to define which bank to precharge.
DQ0~DQ63
In/Out
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
DQS0~DQS7
In/Out
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 DDR2 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 If the module is to be operated in single ended strobe mode, all DQS signals
must be tied on the system board to VSS and DDR2 SDRAM mode registers programmed appropriately.
VDD,VDD
SPD,VSS
Supply
Power supplies for core, I/O, Serial Presence Detect, and ground for the module.
SDA
In/Out
This is a bidirectional pin used to transfer data into or out of the SPD EEPROM. A resistor must be connected to VDD to act
as a pull up.
SCL
Input
This signal is used to clock data into and out of the SPD EEPROM. A resistor may be connected from SCL to VDD to act as
a pull up.
SA0~SA1
Input
Address pins used to select the Serial Presence Detect base address.
TEST
In/Out
The TEST pin is reserved for bus analysis tools and is not connected on normal memory modules(SO-DIMMs).

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.

Note : There is no specific device VDD supply voltage requirement for SSTL-1.8 compliance. However under all conditions VDDQ must be less than or equal
to VDD.
1. The value of VREF may be selected by the user to provide optimum noise margin in the system. Typically the value of VREF is expected to be about 0.5
x VDDQ of the transmitting device and VREF is expected to track variations in VDDQ.
2. Peak to peak AC noise on VREF may not exceed +/-2% VREF(DC).
3. VTT of transmitting device must track VREF of receiving device.
4. AC parameters are measured with VDD, VDDQ and VDDL tied together.

2. At 0 - 85 °C, operation temperature range are the temperature which all DRAM specification will be supported.
3. At 85 - 95 °C operation temperature range, doubling refresh commands in frequency to a 32ms period ( tREFI=3.9 us ) is required, and to enter to self
refresh mode at this temperature range, an EMRS command is required to change internal refresh rate.
