Rev. 1.2 Aug. 2005 512MB, 1GB, 2GB Registered DIMMs DDR2 SDRAM Input/Output Functional Description Symbol Type Function CK0 Input Positive line of the differential pair of system clock inputs that drives input to the on-DIMM PLL. CK0 Input Negative line of the differential pair of system clock inputs that drives the input to the on-DIMM PLL. 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 Power Down mode, or the Self Refresh mode. S0~S1 Input Enables the associated SDRAM command decoder when low and disables decoder when high. When decoder is disabled, new commands are ignored but previous operations continue. These input signals also disable all outputs (except CKE and ODT) of the register(s) on the DIMM when both inputs are high. ODT0~ODT1 Input I/O bus impedance control signals. RAS, CAS, WE Input When sampled at the positive rising edge of the clock, CAS, RAS, and WE define the operation to be executed by the SDRAM. VREF Supply Reference voltage for SSTL_18 inputs VDDQ Supply Isolated power supply for the DDR SDRAM output buffers to provide improved noise immunity BA0~BA1 Input Selects which SDRAM bank of four is activated. A0~A9,A10/AP A11~A13 Input During a Bank Activate command cycle, Address defines the row address. During a Read or Write command cycle, Address defines the column 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 disabled. 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 pre- charged regardless of the state of BA0 or BA1. If AP is low, BA0 and BA1 are used to define which bank to precharge. DQ0~63, CB0~CB7 In/Out Data and Check Bit Input/Output pins DM0~DM8 Input Masks write data when high, issued concurrently with input data. Both DM and DQ have a write latency of one clock once the write command is registered into the SDRAM. V DD, VSS Supply Power and ground for the DDR SDRAM input buffers and core logic DQS0~DQS17 In/Out Positive line of the differential data strobe for input and output data. DQS0~DQS17 In/Out Negative line of the differential data strobe for input and output data. SA0~SA2 Input These signals are tied at the system planar to either V SS or VDDSPD to configure the serial SPD EEPROM 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 VDDSPD to act as a pullup. 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 VDDSPD to act as a pullup. VDDSPD Supply Serial EEPROM positive power supply (wired to a separate power pin at the connector which supports from 1.7 Volt to 3.6 Volt operation). RESET Input The RESET pin is connected to the RST pin on the register and to the OE pin on the PLL. When low, all register outputs will be driven low and the PLL clocks to the DRAMs and register(s) will be set to low level (The PLL will remain synchro- nized with the input clock ) Par_In Input Parity bit for the Address and Control bus. ( “1 “ : Odd, “0 “ : Even) Err_Out Input Parity error found in the Address and Control bus TEST In/Out Used by memory bus analysis tools (unused on memory DIMMs)

Rev. 1.2 Aug. 2005 512MB, 1GB, 2GB Registered DIMMs DDR2 SDRAM 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 s pecification 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. AC & DC Operating Conditions Recommended DC Operating Conditions (SSTL - 1.8) 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.

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 85 - 95 ×C operation temperature range, doubling refresh commands in frequency to a 32ms period ( tREFI=3.9 us ) is requi red, and to enter to self refresh mode at this temperature range, an EMRS command is required to change internal refresh rate. Input DC Logic Level Input AC Logic Level AC Input Test Conditions Notes: 1. Input waveform timing is referenced to the input signal crossing through the V IH/IL(AC) level applied to the device under test. 2. The input signal minimum slew rate is to be maintained over the range from V REF to VIH(AC) min for rising edges and the range from V REF to VIL(AC) max for falling edges as shown in the below figure. 3. AC timings are referenced with input waveforms switching from V IL(AC) to VIH(AC) on the positive transitions and V IH(AC) to VIL(AC) on the negative transitions.
