Input 63, 128 CKE0, CKE1 Input 30, 45, 114, 129 S0#–S3# Input 28–29, 46–47, 112– DQMB0– 113, 130–131 DQMB7 Input Clock: CK is driven by the system clock. All SDRAM input signals are sampled on the positive edge of CK. CK also increments the internal burst counter and controls the output registers. Clock Enable: CKE0 activate (HIGH) and deactivate (LOW) the CK signal. Deactivating the clock provides PRECHARGE POWER-DOWN and SELF REFRESH operation (all device banks idle), ACTIVE POWER-DOWN (row ACTIVE in any device bank) or CLOCK SUSPEND operation (burst access in progress). CKE is synchronous except after the device enters power-down and self refresh modes, where CKE becomes asynchronous until after exiting the same mode. The input buffers, including CK, are disabled during power-down and self refresh modes, providing low standby power. Chip Select: S# enables (registered LOW) and disables (registered HIGH) the command decoder. All commands are masked when S# is registered HIGH. S# is considered part of the command code. Input/Output Mask: DQMB is an input mask signal for write accesses and an output enable signal for read accesses. Input data is masked when DQMB is sampled HIGH during a WRITE cycle. The output buffers are placed in a High-Z state (two-clock latency) when DQMB is sampled HIGH during a READ cycle. Bank Address: BA0 and BA1 define to which device bank the ACTIVE, READ, WRITE, or PRECHARGE command is being applied. Address Inputs: Provide the row address for ACTIVE commands, and the column address and auto precharge bit (A10) for READ/WRITE commands, to select one location out of the memory array in the respective device bank. A10 sampled during a PRECHARGE command determines whether the PRECHARGE applies to once device bank (A10 LOW, device bank selected by BA0, BA1) or all device banks (A10 HIGH). The address inputs also provide the op-code during a MODE REGISTER SET command. Serial Clock for Presence-Detect: SCL is used to synchronize the presence-detect data transfer to and from the module.

This nonvolatile storage device contains 256 bytes. The first 128 bytes can be programmed by Micron to identify the module type and various SDRAM organizations and timing parameters. The remaining 128 bytes of storage are available for use by the customer. System READ/WRITE operations between the master (system logic) and the slave EEPROM device (DIMM) occur via a standard IIC bus using the DIMM’s SCL (clock) and SDA (data) signals, together with SA (2:0), which provide eight unique DIMM/EEPROM addresses. signals CK). Read and write accesses to the SDRAM modules are burst oriented; accesses start at a selected location and continue for a programmed number of locations in a programmed sequence. Accesses begin with the registration of an ACTIVE command, which is then followed by a READ or WRITE command. The address bits registered coincident with the ACTIVE command are used to select the device bank and row to be accessed (BA0, BA1 select the device bank, A0–A11 select the device row). The address bits registered coincident with the READ or WRITE command are used to select the starting column location for the burst access. The modules provide for programmable READ or WRITE burst lengths of 1, 2, 4, or 8 locations, or the full page, with a burst terminate option. An AUTO PRECHARGE function may be enabled to provide a selftimed row precharge that is initiated at the end of the burst sequence. SDRAM modules use an internal pipelined architecture to achieve high-speed operation. This architecture is compatible with the 2n rule of prefetch architectures, but it also allows the column address to be changed on every clock cycle to achieve a highspeed, fully random access. Precharging one device bank while accessing one of the other three device banks will hide the precharge cycles and provide seamless, high-speed, random-access operation. SDRAM modules are designed to operate in 3.3V, low-power memory systems. An auto refresh mode is provided, along with a power-saving, power-down mode. All inputs and outputs are LVTTL-compatible. SDRAM modules offer substantial advances in DRAM operating performance, including the ability to synchronously burst data at a high data rate with automatic column-address generation, the ability to interleave between internal banks in order to hide precharge time and the capability to randomly change column addresses on each clock cycle during a burst access. For more information regarding SDRAM operation, refer to the 128Mb SDRAM component data sheets. PDF: 09005aef8137b07b/Source: 09005aef8137b02d SD8_16C16_32x64AG.fm - Rev. E 12/10 EN Initialization DD and VDDQ (simultaneously) and the clock is stable (stable clock is defined as a signal cycling within timing constraints specified for the clock pin), the SDRAM requires a 100µs delay prior to issuing any command other than a COMMAND INHIBIT or NOP. Starting at some point during this 100µs period and continuing at least through the end of this period, Command Inhibit or NOP commands should be applied. Once the 100µs delay has been satisfied with at least one Command Inhibit or NOP command having been applied, a PRECHARGE command should be applied. All device banks must then be precharged, thereby placing the device in the all banks idle state. Once in the idle state, two AUTO refresh cycles must be performed. After the AUTO refresh cycles are complete, the SDRAM is ready for mode register programming. Because the mode register will power up in an unknown state, it should be loaded prior to applying any operational command.

Idd is dependent on output loading and cycle rates. Specified values are obtained with minimum cycle time and the outputs open. 4. Enables on-chip refresh and address counters. 5. The minimum specifications are used only to indicate cycle time at which proper operation over the full temperature range is ensured (0°C ≤ TA ≤ +70°C). 6. An initial pause of 100µs is required after powerup, followed by two AUTO Refresh commands, before proper device operation is ensured. (VDD and VDDQ must be powered up simultaneously. Vss and VssQ must be at same potential.) The two AUTO Refresh command wake-ups should be repeated any time the tREF refresh requirement is exceeded. 7. AC characteristics assume tT = 1ns. 8. In addition to meeting the transition rate specification, the clock and CKE must transit between VIH and VIL (or between VIL and VIH) in a monotonic manner. 9. Outputs measured at 1.5V with equivalent load: Q 50pF 10. tHZ defines the time at which the output achieves the open circuit condition; it is not a reference to VOH or VOL. The last valid data element will meet t OH before going High-Z. 11. AC timing and Idd tests have VIL = 0V and VIH = 3V, with timing referenced to 1.5V crossover point. If the input transition time is longer than 1 ns, then the timing is referenced at VIL (MAX) and VIH (MIN) and no longer at the 1.5V crossover point. 12. Other input signals are allowed to transition no more than once every two clocks and are otherwise at valid VIH or VIL levels. 13. IDD specifications are tested after the device is properly initialized. 14. Timing actually specified by tCKS; clock(s) specified as a reference only at minimum cycle rate. 15. Timing actually specified by tWR plus tRP; clock(s) specified as a reference only at minimum cycle rate. 16. Timing actually specified by tWR. 17. Required clocks are specified by JEDEC functionality and are not dependent on any timing parameter. 18. The IDD current will increase or decrease proportionally according to the amount of frequency alteration for the test condition. 19. Address transitions average one transition every two clocks. 20. CLK must be toggled a minimum of two times during this period. 21. Based on tCK = 10ns for -10E, and tCK = 7.5ns for 133 and -13E. 22. VIH overshoot: VIH (MAX) = VDDQ + 2V for a pulse width ≤ 3ns, and the pulse width cannot be greater than one third of the cycle rate. VIL undershoot: VIL (MIN) = -2V for a pulse width ≤ 3ns. 23. The clock frequency must remain constant (stable clock is defined as a signal cycling within timing constraints specified for the clock pin) during access or precharge states (READ, WRITE, including tWR, and PRECHARGE commands). CKE may be used to reduce the data rate. 24. Auto precharge mode only. The precharge timing budget (tRP) begins 7ns for -13E; 7.5ns for -133 and 7ns for -10E after the first clock delay, after the last WRITE is executed. May not exceed limit set for precharge mode. 25. Precharge mode only. 26. JEDEC and PC100 specify three clocks. 27. tAC for -133/-13E at CL = 3 with no load is 4.6ns and is guaranteed by design. 28. Parameter guaranteed by design. 29. For -10E, CL= 2 and tCK = 10ns; for -133, CL = 3 and tCK = 7.5ns; for -13E, CL = 2 and tCK = 7.5ns. 30. CKE is HIGH during refresh command period t RFC (MIN) else CKE is LOW. The Idd6 limit is actually a nominal value and does not result in a fail value. 31. The value of tRAS used in -13E speed grade module SPDs is calculated from tRC - tRP = 45ns. 32. Refer to device data sheet for timing waveforms. 33. Leakage number reflects the worst case leakage possible through the module pin, not what each memory device contributes. SPD Clock and Data Conventions SPD Acknowledge Data states on the SDA line can change only during SCL LOW. SDA state changes during SCL HIGH are reserved for indicating start and stop conditions (as shown in Figure 7, Data Validity, and Figure 8, Definition of Start and Stop). SPD Start Condition All commands are preceded by the start condition, which is a HIGH-to-LOW transition of SDA when SCL is HIGH. The SPD device continuously monitors the SDA and SCL lines for the start condition and will not respond to any command until this condition has been met. SPD Stop Condition All communications are terminated by a stop condition, which is a LOW-to-HIGH transition of SDA when SCL is HIGH. The stop condition is also used to place the SPD device into standby power mode.

The SPD EEPROM WRITE cycle time (tWRC) is the time from a valid stop condition of a write sequence to the end of the EEPROM internal erase/program cycle. During the WRITE cycle, the EEPROM bus interface circuit is disabled, SDA remains HIGH due to pull-up resistor, and the EEPROM does not respond to its slave address.
