Rev. 1.3 Aug. 2005 512MB, 1GB, 2GB Registered DIMMs DDR2 SDRAM Input/Output Functional Description Symbol Type Function CK0 Input 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 precharged 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. VDD, 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 VSS 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 RESET Input Positive line of the differential pair of system clock inputs that drives input to the on-DIMM PLL. 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). 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 synchronized 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. 1.3 Aug. 2005 512MB, 1GB, 2GB Registered DIMMs DDR2 SDRAM Functional Block Diagram: 512MB, 64Mx72 Module(populated as 1 rank of x8 DDR2 SDRAMs) M393T6553BG(Z)3 / M393T6553BG(Z)0 RS0 DQS0 DQS0 DM0/DQS9 NC/DQS9 DQS4 DQS4 DM4/DQS13 NC/DQS13 DQ0 DQ1 DQ2 DQ3 DQ4 DQ5 DQ6 DQ7 DM/ NU/ CS RDQS RDQS I/O 0 I/O 1 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 DQS DQS DQ32 DQ33 DQ34 DQ35 DQ36 DQ37 DQ38 DQ39 D0 DQS1 DQS1 DM1/DQS10 NC/DQS10 DM/ NU/ CS RDQS RDQS I/O 0 I/O 1 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 DQS DQS D4 DQS5 DQS5 DM5/DQS14 NC/DQS14 DQ8 DQ9 DQ10 DQ11 DQ12 DQ13 DQ14 DQ15 DM/ NU/ CS RDQS RDQS I/O 0 I/O 1 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 DQS DQS DQ40 DQ41 DQ42 DQ43 DQ44 DQ45 DQ46 DQ47 D1 DQS2 DQS2 DM2/DQS11 NC/DQS11 DM/ NU/ CS RDQS RDQS I/O 0 I/O 1 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 DQS DQS D5 DQS6 DQS6 DM6/DQS15 NC/DQS15 DQ16 DQ17 DQ18 DQ19 DQ20 DQ21 DQ22 DQ23 DM/ NU/ CS RDQS RDQS I/O 0 I/O 1 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 DQS DQS DQ48 DQ49 DQ50 DQ51 DQ52 DQ53 DQ54 DQ55 D2 DQS3 DQS3 DM3/DQS12 NC/DQS12 DM/ NU/ CS RDQS RDQS I/O 0 I/O 1 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 DQS DQS D6 DQS7 DQS7 DM7/DQS16 NC/DQS16 DQ24 DQ25 DQ26 DQ27 DQ28 DQ29 DQ30 DQ31 DM/ NU/ CS RDQS RDQS I/O 0 I/O 1 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 DQS DQS DQ56 DQ57 DQ58 DQ59 DQ60 DQ61 DQ62 DQ63 D3 DQS8 DQS8 DM8/DQS17 NC/DQS17 Serial PD SCL CB0 CB1 CB2 CB3 CB4 CB5 CB6 CB7 DM/ NU/ CS RDQS RDQS I/O 0 I/O 1 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 DQS DQS D8 1:1 R E G I S T E R RESET RST A1 A2 SA0 SA1 SA2 CK0 CK0 RESET S0* BA0-BA1 A0-A13 RAS CAS WE CKE0 ODT0 SDA WP A0 P L L OE RSO-> CS : DDR2 SDRAMs D0-D8 RBA0-RBA1 -> BA0-BA1 : DDR2 SDRAMs D0-D8 RA0-RA13 -> A0-A13 : DDR2 SDRAMs D0-D8 RRAS -> RAS : DDR2 SDRAMs D0-D8 RCAS -> CAS : DDR2 SDRAMs D0-D8 RWE -> WE : DDR2 SDRAMs D0-D8 RCKE0 -> CKE : DDR2 SDRAMs D0-D8 RODT0 -> ODT0 : DDR2 SDRAMs D0-D8 DM/ NU/ CS RDQS RDQS I/O 0 I/O 1 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 DQS DQS D7 VDDSPD Serial PD VDD/VDDQ D0 - D8 VREF D0 - D8 VSS D0 - D8 PCK0-PCK6, PCK8, PCK9 -> CK : DDR2 SDRAMs D0-D8 PCK0-PCK6, PCK8, PCK9 -> CK : DDR2 SDRAMs D0-D8 PCK7 -> CK : Register PCK7 -> CK : Register Notes : 1.

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.

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.

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.

The clock delay from the input of the PLL clock to the input of any DDR2 SDRAM or register will be set to 0ns (nominal). Input, output, and feedback clock lines are terminated from line to line as shown, and not from line to ground. Only one PLL output is shown per output type. Any additional PLL outputs will be wired in a similar manner. Termination resistors for the PLL feedback path clocks are located as close to the input pin of the PLL as possible.
