Refer to Pin Assignment tables on page 3 for more information PIN NUMBERS SYMBOL 118, 119, 120 WE#, CAS#, RAS# TYPE DESCRIPTION Input Command Inputs: RAS#, CAS#, and WE# (along with S#) define the command being entered. 35, 37, 158, 160 CK0, CK0#, Input Clock: CK, CK# are differential clock inputs. All address and CK1, CK1#, control input signals are sampled on the crossing of the positive edge of CK,and negative edge of CK#. Output data (DQs and DQS) is referenced to the crossings of CK and CK#. 96 CKE0 Input Clock Enable: CKE HIGH activates and CKE LOW deactivates the internal clock, input buffers and output drivers. Taking CKE LOW provides PRECHARGE POWER-DOWN and SELF REFRESH operations (all device banks idle), or ACTIVE POWERDOWN (row ACTIVE in any device bank).CKE is synchronous for POWER-DOWN entry and exit, and for SELF REFRESH entry. CKE is asynchronous for SELF REFRESH exit and for disabling the outputs. CKE must be maintained HIGH throughout read and write accesses. Input buffers (excluding CK, CK# and CKE) are disabled during POWER-DOWN. Input buffers (excluding CKE) are disabled during SELF REFRESH. CKE is an SSTL_2 input but will detect an LVCMOS LOW level after VDD is applied and until CKE is first brought HIGH. After CKE is brought HIGH, it becomes an SSTL_2 input only. 121 S0# Input Chip Selects: 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. 116, 117 BA0, BA1 Input Bank Address: BA0 and BA1 define to which device bank an ACTIVE, READ, WRITE, or PRECHARGE command is being applied. A0–A11 (128MB) Input Address Inputs: Provide the row address for ACTIVE 99 (256MB, 512MB), 100, 101, 102, 105, 106, 107, A0–A12 (256MB, 512MB) commands, and the column address and auto precharge bit 108, 109, 110, 111, 112, (A10) for READ/WRITE commands, to select one location out 115 of the memory array in the respective device bank. A10 sampled during a PRECHARGE command determines whether the PRECHARGE applies to one 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. BA0 and BA1 define which mode register (mode register or extended mode register) is loaded during the LOAD MODE REGISTER command. 11, 25, 47, 61, 133, 147, DQS0–DQS7 Input/ Data Strobe: Output with READ data, input with WRITE data. 169, 183 Output DQS is edge-aligned with READ data, centered in WRITE data.

An auto refresh mode is provided, along with a power-saving power-down mode. All inputs are compatible with the JEDEC Standard for SSTL_2. All outputs are SSTL_2, Class II compatible. For more information regarding DDR SDRAM operation, refer to the 128Mb, 256Mb, or 512Mb DDR SDRAM component data sheets. The MT8VDDT1664H, MT8VDDT3264H, and MT8VDDT6464H are high-speed CMOS, dynamic random-access, 128MB, 256MB, and 512MB memory modules organized in x64 configuration. DDR SDRAM modules use internally configured quad-bank DDR SDRAMs. DDR SDRAM modules use a double data rate architecture to achieve high-speed operation. The double data rate architecture is essentially a 2n-pre-fetch architecture with an interface designed to transfer two data words per clock cycle at the I/O pins. A single read or write access for the DDR SDRAM module effectively consists of a single 2n-bit wide, one-clock-cycle data transfer at the internal DRAM core and two corresponding n-bit wide, one-half-clock-cycle data transfers at the I/O pins. A bidirectional data strobe (DQS) is transmitted externally, along with data, for use in data capture at the receiver. DQS is an intermittent strobe transmitted by the DDR SDRAM during READs and by the memory controller during WRITEs. DQS is edge-aligned with data for READs and center-aligned with data for WRITEs. DDR SDRAM modules operate from differential clock inputs (CK and CK#); the crossing of CK going HIGH and CK# going LOW will be referred to as the positive edge of CK. Commands (address and control signals) are registered at every positive edge of CK. Input data is registered on both edges of DQS, and output data is referenced to both edges of DQS, as well as to both edges of CK. Read and write accesses to DDR 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 device bank; A0–A11 select device row (128MB), A0–A12 select device row (256MB, 512MB). The address bits registered coincident with the READ or WRITE command are used to select the device bank and the starting device column location for the burst access. DDR SDRAM modules provide for programmable READ or WRITE burst lengths of 2, 4, or 8 locations. An auto precharge function may be enabled to provide a self-timed row precharge that is initiated at the end of the burst access. The pipelined, multibank architecture of DDR SDRAM modules allows for concurrent operation, pdf: 09005aef8092973f, source: 09005aef80921669 DD8C16_32_64x64HG.fm - Rev. B 9/04 EN Serial Presence-Detect Operation DDR SDRAM modules incorporate serial presencedetect (SPD). The SPD function is implemented using a 2,048-bit EEPROM. 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 I2C bus using the DIMM’s SCL (clock) and SDA (data) signals, together with SA (2:0), which provide eight unique DIMM/EEPROM addresses. Write protect (WP) is tied to ground on the module, permanently disabling hardware write protect. Mode Register Definition The mode register is used to define the specific mode of operation of DDR SDRAM devices. This definition includes the selection of a burst length, a burst type, a CAS latency and an operating mode, as shown in Figure 4, Mode Register Definition Diagram, on page 8. The mode register is programmed via the MODE REGISTER SET command (with BA0 = 0 and BA1 = 0) and will retain the stored information until it is programmed again or the device loses power (except for bit A8, which is self-clearing). Reprogramming the mode register will not alter the contents of the memory, provided it is performed correctly. The mode register must be loaded (reloaded) when all device banks are idle and no bursts are in progress, and the controller must wait the specified time before initiating the subsequent operation. Violating either of these requirements will result in unspecified operation. Mode register bits A0–A2 specify the burst length, A3 specifies the type of burst (sequential or interleaved), A4–A6 specify the CAS latency, and A7–A11 (128MB) or A7–A12 (256MB, 512MB) specify the operating mode. 7 Micron Technology, Inc., reserves the right to change products or specifications without notice. ©2004 Micron Technology, Inc.

The burst length determines the maximum number of column locations that can be accessed for a given READ or WRITE command. Burst lengths of 2, 4, or 8 locations are available for both the sequential and the interleaved burst types. Reserved states should not be used, as unknown operation or incompatibility with future versions may result. When a READ or WRITE command is issued, a block of columns equal to the burst length is effectively selected. All accesses for that burst take place within this block, meaning that the burst will wrap within the block if a boundary is reached. The block is uniquely selected by A1–Ai when the burst length is set to two, by A2–Ai when the burst length is set to four and by A3–Ai when the burst length is set to eight (where Ai is the most significant column address bit for a given configuration; see Note 5 for Figure 6, Burst Definition Table, on page 9). The remaining (least significant) address bit(s) is (are) used to select the starting location within the block. The programmed burst length applies to both READ and WRITE bursts. 128MB Module Address Bus BA1 BA0 A11 A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 A0 13 12 11 10 9 8 7 6 5 4 3 2 1 0 Operating Mode CAS Latency BT Burst Length 0* 0* Mode Register (Mx) * M13 and M12 (BA1and BA0) must be “0, 0” to select the base mode register (vs. the extended mode register). 256MB, 512MB Module Address Bus BA1 BA0 A12 A11 A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 A0 14 13 12 11 10 9 8 Operating Mode 0* 0* 7 6 5 4 3 2 1 0 CAS Latency BT Burst Length * M14 and M13 (BA1 and BA0) must be “0, 0” to select the base mode register (vs. the extended mode register).

The latency can be set to 2 or 2.5 clocks, as shown in Figure 5, CAS Latency Diagram. If a READ command is registered at clock edge n, and the latency is m clocks, the data will be available nominally coincident with clock edge n + m. Table 7, CAS Latency (CL) Table, on page 9, indicates the operating frequencies at which each CAS latency setting can be used.

A DLL reset is initiated by issuing a MODE REGISTER SET command with bits A7 and A9–A11 (128MB), or A7 and A9–A12 (256MB, 512MB) each set to zero, bit A8 set to one, and bits A0–A6 set to the desired values. Although not required by the Micron device, JEDEC specifications recommend when a LOAD MODE REGISTER command is issued to reset the DLL, it should always be followed by a LOAD MODE REGISTER command to select normal operating mode. All other combinations of values for A7–A11 (128MB), or A7–A12 (256MB, 512MB) are reserved for future use and/or test modes.

The enabling of the DLL should always be followed by a LOAD MODE REGISTER command to the mode register (BA0/BA1 both LOW) to reset the DLL. The extended mode register must be loaded when all device banks are idle and no bursts are in progress, and the controller must wait the specified time before initiating any subsequent operation. Violating either of these requirements could result in unspecified operation. 128MB Module BA1 BA0 A11 A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 A0 13 12 11 10 9 8 7 6 5 4 Operating Mode 01 11 3 2 1 0 Address Bus Extended Mode Register (Ex) DS DLL 256MB, 512MB Modules BA1 BA0 A12 A11 A10 A9 A8 A7 A6 A5 A4 A3 A2 A1 A0 Address Bus DLL Enable/Disable The DLL must be enabled for normal operation.

Tests for AC timing, IDD, and electrical AC and DC characteristics may be conducted at nominal reference/supply voltage levels, but the related specifications and device operation are guaranteed for the full voltage range specified. 3. Outputs measured with equivalent load: the fact that they are matched in loading. 12. For slew rates < 1 V/ns and ≥ to 0.5 Vns. If the slew rate is < 0.5V/ns, timing must be derated: tIS has an additional 50ps per each 100 mV/ns reduction in slew rate from 500 mV/ns, while tIH is unaffected. If the slew rate exceeds 4.5 V/ns, functionality is uncertain. For -335, slew rates must be ≥ 0.5 V/ns. 13. The CK/CK# input reference level (for timing referenced to CK/CK#) is the point at which CK and CK# cross; the input reference level for signals other than CK/CK# is VREF. 14. Inputs are not recognized as valid until VREF stabilizes. Exception: during the period before VREF stabilizes, CKE ≤ 0.3 x VDDQ is recognized as LOW. 15. The output timing reference level, as measured at the timing reference point indicated in Note 3, is VTT. 16. tHZ and tLZ transitions occur in the same access time windows as valid data transitions. These parameters are not referenced to a specific voltage level, but specify when the device output is no longer driving (HZ) or begins driving (LZ). 17. The intent of the “Don’t Care” state after completion of the postamble is that the DQS-driven signal should either be HIGH, LOW, or High-Z and that any signal transition within the input switching region must follow valid input requirements. If DQS transitions HIGH, above DC VIH (MIN) then it must not transition LOW, below DC VIH, prior to t DQSH (MIN). 18. This is not a device limit. The device will operate with a negative value, but system performance could be degraded due to bus turnaround. 19. It is recommended that DQS be valid (HIGH or LOW) on or before the WRITE command. The case shown (DQS going from High-Z to logic LOW) applies when no WRITEs were previously in progress on the bus. If a previous WRITE was in progress, DQS could be HIGH during this time, depending on tDQSS. 20. MIN (tRC or tRFC) for IDD measurements is the smallest multiple of tCK that meets the minimum absolute value for the respective parameter. tRAS (MAX) for IDD measurements is the largest multiple of tCK that meets the maximum absolute value for tRAS. 21. The refresh period is 64ms. This equates to an average refresh rate of 15.625µs (128MB) or 7.8125µs (256MB, 512MB). However, an AUTO REFRESH command must be asserted at least once every 140.6µs (128MB) or 70.3µs (256MB, VTT Output (VOUT) 50Ω Reference Point 30pF 4. AC timing and IDD tests may use a VIL-to-VIH swing of up to 1.5V in the test environment, but input timing is still referenced to VREF (or to the crossing point for CK/CK#), and parameter specifications are guaranteed for the specified AC input levels under normal use conditions. The minimum slew rate for the input signals used to test the device is 1V/ns in the range between VIL (ACV) and VIH (AC). 5. The AC and DC input level specifications are as defined in the SSTL_2 Standard (i.e., the receiver will effectively switch as a result of the signal crossing the AC input level, and will remain in that state as long as the signal does not ring back above [below] the DC input LOW [HIGH] level). 6. VREF is expected to equal VDDQ/2 of the transmitting device and to track variations in the DC level of the same. Peak-to-peak noise (non-common mode) on VREF may not exceed ±2 percent of the DC value. Thus, from VDDQ/2, VREF is allowed ±25mV for DC error and an additional ±25mV for AC noise. This measurement is to be taken at the nearest VREF by-pass capacitor. 7. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to VREF and must track variations in the DC level of VREF. 8. IDD is dependent on output loading and cycle rates. Specified values are obtained with minimum cycle time at CL = 2 for -262, -26A, and -202, CL = 2.5 for -335 and -265 with the outputs open. 9. Enables on-chip refresh and address counters. 10. IDD specifications are tested after the device is properly initialized, and is averaged at the defined cycle rate. 11. This parameter is sampled. VDD = +2.5V ±0.2V, VDDQ = +2.5V ±0.2V, VREF = VSS, f = 100 MHz, TA = 25°C, VOUT (DC) = VDDQ/2, VOUT (peak to peak) = 0.2V.

The valid data window is derived by achieving other specifications: tHP (tCK/2), tDQSQ, and tQH (tQH = tHP - tQHS). The data valid window derates directly porportional with the clock duty cycle and a practical data valid window can be derived. The clock is allowed a maximum duty cycle variation of 45/55, beyond which functionality is uncertain. Figure 7, Derating Data Valid Window (tQH - tDQSQ), shows the derating curves for duty cycles ranging between 50/50 and 45/55. Each byte lane has a corresponding DQS. This limit is actually a nominal value and does not result in a fail value. CKE is HIGH during REFRESH command period (tRFC [MIN]) else CKE is LOW (i.e., during standby). To maintain a valid level, the transitioning edge of the input must: 26. 27. 28. 29. a. Sustain a constant slew rate from the current AC level through to the target AC level, VIL (AC) or VIH (AC). b. Reach at least the target AC level. c. After the AC target level is reached, continue to maintain at least the target DC level, VIL (DC) or VIH (DC). JEDEC specifies CK and CK# input slew rate must be ≥ 1V/ns (2V/ns differentially). DQ and DM input slew rates must not deviate from DQS by more than 10 percent. If the DQ/ DM/DQS slew rate is less than 0.5 V/ns, timing must be derated: 50ps must be added to tDS and t DH for each 100mv/ns reduction in slew rate. If slew rate exceeds 4 V/ns, functionality is uncertain. For -335, slew rates must be ≥ 0.5 V/ns. VDD must not vary more than 4 percent if CKE is not active while any device bank is active. The clock is allowed up to ±150ps of jitter. Each timing parameter is allowed to vary by the same amount.

READs and WRITEs with auto precharge are not allowed to be issued until tRAS(MIN) can be satisfied prior to the internal precharge command being issued. 32. Any positive glitch in the nominal voltage must be less than 1/3 of the clock and not more than +400mV or 2.9V maximum, whichever is less. Any negative glitch must be less than 1/3 of the clock cycle and not exceed either -300mV or 2.2V minimum, whichever is more positive. 33. Normal Output Drive Curves: a. The full variation in driver pull-down current from minimum to maximum process, temperature and voltage will lie within the outer bounding lines of the V-I curve of Figure 8, Pull-Down Characteristics. b. The variation in driver pull-down current within nominal limits of voltage and temperature is expected, but not guaranteed, to lie within the inner bounding lines of the V-I curve of Figure 8, Pull-Down Characteristics. c. The full variation in driver pull-up current from minimum to maximum process, temperature and voltage will lie within the outer bounding lines of the V-I curve of Figure 9, Pull-Up Characteristics. d. The variation in driver pull-up current within nominal limits of voltage and temperature is expected, but not guaranteed, to lie within the inner bounding lines of the V-I curve of Figure 9, Pull-Up Characteristics. e. The full variation in the ratio of the maximum to minimum pull-up and pull-down current should be between 0.71 and 1.4, for device drain-to-source voltages from 0.1V to 1.0V, and at the same voltage and temperature. f. The full variation in the ratio of the nominal pull-up to pull-down current should be unity ±10 percent, for device drain-to-source voltages from 0.1V to 1.0V. The voltage levels used are derived from a minimum VDD level and the referenced test load. In practice, the voltage levels obtained from a properly terminated bus will provide significantly different voltage values. VIH overshoot: VIH (MAX) = VDDQ + 1.5V for a pulse width ≤ 3ns and the pulse width can not be greater than 1/3 of the cycle rate. VIL undershoot: VIL (MIN) = -1.5V for a pulse width ≤ 3ns and the pulse width can not be greater than 1/3 of the cycle rate. VDD and VDDQ must track each other. t HZ (MAX) will prevail over tDQSCK (MAX) + t RPST (MAX) condition. tLZ (MIN) will prevail over tDQSCK (MIN) + tRPRE (MAX) condition. t RPST end point and tRPRE begin point are not referenced to a specific voltage level but specify when the device output is no longer driving (tRPST), or begins driving (tRPRE). During initialization, VDDQ, VTT, and VREF must be equal to or less than VDD + 0.3V. Alternatively, VTT may be 1.35V maximum during power up, even if VDD/VDDQ are 0V, provided a minimum of 42Ω of series resistance is used between the VTT supply and the input pin. 34. 35. 36. 37. 38. 39.

This is followed by 200 clock cycles (before READ commands). Leakage number reflects the worst case leakage possible through the module pin, not what each memory device contributes. When an input signal is HIGH or LOW, it is defined as a steady state logic high or logic low.

Simultaneously apply power to VDD and VDDQ. 2. Apply VREF and then VTT power. 3. Assert and hold CKE at a LVCMOS logic low. 4. Provide stable CLOCK signals. 5. Wait at least 200µs. 6.

SDA state changes during SCL HIGH are reserved for indicating start and stop conditions (as shown in Figure 11, Data Validity, and Figure 12, Definition of Start and Stop). Acknowledge is a software convention used to indicate successful data transfers. The transmitting device, either master or slave, will release the bus after transmitting eight bits. During the ninth clock cycle, the receiver will pull the SDA line LOW to acknowledge that it received the eight bits of data (as shown in Figure 13, Acknowledge Response from Receiver). The SPD device will always respond with an acknowledge after recognition of a start condition and its slave address. If both the device and a WRITE operation have been selected, the SPD device will respond with an acknowledge after the receipt of each subsequent eight-bit word. In the read mode the SPD device will transmit eight bits of data, release the SDA line and monitor the line for an acknowledge. If an acknowledge is detected and no stop condition is generated by the master, the slave will continue to transmit data. If an acknowledge is not detected, the slave will terminate further data transmissions and await the stop condition to return to standby power mode. 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.
