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~BA2 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 BA0BAn 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(SODIMMs). 6 of 20 Rev. 1.4 March 2007 SODIMM DDR2 SDRAM 7.0 Functional Block Diagram : 7.1 1GB, 128Mx64 Module - M470T2864AZ3 (Populated as 2 rank of x16 DDR2 SDRAMs) 3Ω + 5% ODT1 ODT0 CKE1 CKE0 S1 S0 DQS0 DQS0 DM0 DQS1 DQS1 DM1 DQS2 DQS2 DM2 DQS3 DQS3 DM3 DQ0 DQ1 DQ2 DQ3 DQ4 DQ5 DQ6 DQ7 DQ8 DQ9 DQ10 DQ11 DQ12 DQ13 DQ14 DQ15 DQ16 DQ17 DQ18 DQ19 DQ20 DQ21 DQ22 DQ23 DQ24 DQ25 DQ26 DQ27 DQ28 DQ29 DQ30 DQ31 LDQS CS C K LDQS E LDM I/O 0 I/O 1 D0 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 UDQS UDQS UDM I/O 8 I/O 9 I/O 10 I/O 11 I/O 12 I/O 13 I/O 14 I/O 15 O D T LDQS CS C K LDQS E LDM I/O 0 I/O 1 D1 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 UDQS UDQS UDM I/O 8 I/O 9 I/O 10 I/O 11 I/O 12 I/O 13 I/O 14 I/O 15 O D T LDQS CS C K LDQS E LDM I/O 0 I/O 1 D4 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 UDQS UDQS UDM I/O 8 I/O 9 I/O 10 I/O 11 I/O 12 I/O 13 I/O 14 I/O 15 O D T LDQS CS C K LDQS E LDM I/O 0 I/O 1 D5 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 UDQS UDQS UDM I/O 8 I/O 9 I/O 10 I/O 11 I/O 12 I/O 13 I/O 14 I/O 15 O D T DQS4 DQS4 DM4 DQS5 DQS5 DM5 DQS6 DQS6 DM6 DQS7 DQS7 DM7 DQ32 DQ33 DQ34 DQ35 DQ36 DQ37 DQ38 DQ39 DQ40 DQ41 DQ42 DQ43 DQ44 DQ45 DQ46 DQ47 DQ48 DQ49 DQ50 DQ51 DQ52 DQ53 DQ54 DQ55 DQ56 DQ57 DQ58 DQ59 DQ60 DQ61 DQ62 DQ63 LDQS CS C K LDQS E LDM I/O 0 I/O 1 D2 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 UDQS UDQS UDM I/O 8 I/O 9 I/O 10 I/O 11 I/O 12 I/O 13 I/O 14 I/O 15 O D T LDQS CS C K LDQS E LDM I/O 0 I/O 1 D6 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 UDQS UDQS UDM I/O 8 I/O 9 I/O 10 I/O 11 I/O 12 I/O 13 I/O 14 I/O 15 O D T LDQS CS C K LDQS E LDM I/O 0 I/O 1 D3 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 UDQS UDQS UDM I/O 8 I/O 9 I/O 10 I/O 11 I/O 12 I/O 13 I/O 14 I/O 15 O D T LDQS CS C K LDQS E LDM I/O 0 I/O 1 D7 I/O 2 I/O 3 I/O 4 I/O 5 I/O 6 I/O 7 UDQS UDQS UDM I/O 8 I/O 9 I/O 10 I/O 11 I/O 12 I/O 13 I/O 14 I/O 15 O D T 3Ω + 5% BA0 - BA2 DDR2 SDRAMs D0 - D7 A0 - A13 DDR2 SDRAMs D0 - D7 RAS DDR2 SDRAMs D0 - D7 CAS DDR2 SDRAMs D0 - D7 WE DDR2 SDRAMs D0 - D7 SCL SA0 SA1 SCL A0 A1 A2 SPD SDA WP * Clock Wiring VDDSPD Serial PD VREF DDR2 SDRAMs D0 - D7 VDD DDR2 SDRAMs D0 - D7, VDD and VDDQ VSS DDR2 SDRAMs D0 - D7, SPD Clock Input DDR2 SDRAMs *CK0/CK0 *CK1/CK1 4 DDR2 SDRAMs 4 DDR2 SDRAMs * Wire per Clock Loading Table/Wiring Diagrams 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. 9.0 AC & DC Operating Conditions 9.1 Recommended DC Operating Conditions (SSTL - 1.8) Symbol Parameter Rating Min. Typ. Max.

Max. 1.7 3.6 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. 5. SO-DIMMs that include an optional temperature sensor may require a restricted VDDSPD operating voltage range for proper operation of the temperature sensor. Refer to the thermal sensor specification for details regarding the supported voltage range. All other functions of the SO-DIMM SPD are supported across the full VDDSPD range. 10 of 20 Rev. 1.4 March 2007 SODIMM DDR2 SDRAM 9.2 Operating Temperature Condition Symbol Parameter Rating Units Notes TOPER Operating Temperature 0 to 95 °C 1, 2, 3 Note : 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 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. 9.3 Input DC Logic Level Symbol Parameter Min.

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.
