DDR2 SDRAM
Input/Output Functional Description
Symbol
Type
Function
CK0-CK2
CK0-CK2
Input
CK and CK are differential clock inputs. All the SDRAM addr/cntl inputs are sampled on the crossing
of positive edge of CK and negative edge of CK. Output (read) data is reference to the crossing of
CK and CK (Both directions of crossing)
CKE0-CKE1
Input
Activates the SDRAM CK signal when high and deactivates the CK Signal When low. By deactivating the clocks, CKE low initiates the Powe Down mode, or the Self-Refresh mode
S0-S1
Input
Enables the associated SDRAM command decoder when low and disables the command decoder
when high. When the command decoder is disbled, new command are ignored but previous operations continue. This signal provides for external rank selection on systems with multiple ranks
RAS, CAS, WE
Input
RAS, CAS, and WE (ALONG WITH CS) define the command being entered.
ODT0-ODT1
Input
When high, termination resistance is enabled for all DQ, DQ and DM pins, assuming the function is
enabled in the Extended Mode Register Set (EMRS).
VREF
Supply
Reference voltage for SSTL 18 inputs.
VDDQ
Supply
Power supply for the DDR II SDRAM output buffers to provide improved noise immunity. For all current DDR2 unbuffered DIMM designs, VDDQ shares the same power plane as VDD pins.
BA0-BA1
Input
Selects which SDRAM BANK of four is activated.
During a Bank Activate command cycle, Address input defines the row address (RA0-RA13)
During a Read or Write command cycle, Address input defines the colum address, 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, BA1 defines the bank to be precharged. If
AP is low, autoprecharge is disbled. During a precharge command cycle, AP is used in conjunction
with BA0, BA1 to control which bank(s) to precharge. If AP is high, all banks will be precharged
regardless of the state of BA0, BA1. If AP is low, BA0, BA1are used to define which bank to precharge.
A0-A13
Input
DQ0-DQ63
CB0-CB7
In/Out
DM0-DM8
Input
VDD,VSS
Supply
Power and ground for DDR2 SDRAM input buffers, and core logic. VDD and VDDQ pins are tied to
VDD/VDDQ planes on these modules.
DQS0-DQS8
DQS0-DQS8
In/Out
Data strobe for input and output data. For Rawcards using x16 orginized DRAMs DQ0-7 connect to
the LDQS pin of the DRAMs and DQ8-17 connect to the UDQS pin of the DRAM
SA0-SA2
Input
These signals and tied at the system planar to either VSS or VDD to configure the serial SPD EERPOM address range.
SDA
In/Out
This bidirectional pin is used to transfer data into or out of the SPD EEPROM. A resistor must be
connected from the SDA bus line to VDD to act as a pullup on the system board.
SCL
Input
This signal is used to clock data into and out of the SPD EEPROM. A resistor may be connected
from the SCL bus time to VDD to act as a pullup onthe system board.
VDD SPD
Supply
Power supply for SPD EEPROM. This supply is separate from the VDD/VDDQ power plane.
EEPROM supply is operable from 1.7V to 3.6V.
Data and Check Bit Input/Output pins.
DM is an input mask signal for write data. Input data is masked when DM is sampled High coincident
with that input data during a write access. DM is sampled on both edges of DQS. Although DM pins
are input only, the DM loading matches the DQ and DQS loading.

Notes
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.

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 VDDDL tied together.

1. Operating Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer
to JESD51.2 standard.
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.

2. The input signal minimum slew rate is to be maintained over the range from VREF to VIH(AC) min for rising edges and the range from VREF
to VIL(AC) max for falling edges as shown in the below figure.
3. AC timings are referenced with input waveforms switching from VIL(AC) to VIH(AC) on the positive transitions and VIH(AC) to VIL(AC) on
the negative transitions.
