NT1GD72S4PA1FU are 1GB modules with ECC organized as dual ranks using eighteen 128Mx4 BGA devices. Depending on the speed grade, these DIMMs are intended for use in applications operating up to 166 MHz clock speeds and achieves high-speed data transfer rates of up to 333 MHz. Prior to any access operation, the device CAS latency and burst type/ length/operation type must be programmed into the DIMM by address inputs and I/O inputs BA0 and BA1 using the mode register set cycle. The DIMM uses a serial EEPROM and through the use of a standard IIC protocol the serial presence-detect implementation (SPD) can be accessed. The first 128 bytes of the SPD data are programmed with the module characteristics as defined by JEDEC and the remaining are available for use by the customer.

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 inputs and output timing for read operations is synchronized to the input clock. Activates the DDR 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. Enables the associated DDR SDRAM command decoder when low and disables the (SSTL) Active Low RAS, CAS, WE (SSTL) Active Low VREF Supply VDDQ Supply BA0, BA1 (SSTL) S0, S1 command decoder when high. When the command decoder is disabled, new commands are ignored but previous operations continue. Physical Bank 0 is selected by S0; Bank 1 is selected by S1. When sampled at the positive rising edge of the clock, RAS, CAS, WE define the operation to be executed by the SDRAM. Reference voltage for SSTL-2 inputs Isolated power supply for the DDR SDRAM output buffers to provide improved noise immunity - Selects which SDRAM bank is to be active. During a Bank Activate command cycle, A0-A12 defines the row address (RA0-RA12) when sampled at the rising clock edge. During a Read or Write command cycle, A0-A9 defines the column address (CA0-CA9) when sampled at the rising clock edge. In addition to the column address, AP is used to A0 - A9 A10/AP A11, A12 (SSTL) - invoke auto-precharge operation at the end of the Burst Read or Write cycle. If AP is high, auto-precharge is selected and BA0/BA1 defines the bank to be precharged. If AP is low, auto-precharge 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 4 banks will be precharged regardless of the state of BA0/BA1. If AP is low, then BA0/BA1 are used to define which bank to pre-charge.

Edge aligned with read data, centered on write data. Used to capture write data. Data Check Bit Input/Output pins. Used on ECC modules and is not used on x64 modules. 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. DM8 is associated with check bits CB0-CB7, and is not used on x64 modules. Power and ground for the DDR SDRAM input buffers and core logic Address inputs. Connected to either VDD or VSS on the system board to configure the Serial Presence Detect EEPROM address. This bi-directional pin is used to transfer data into or out of the SPD EEPROM. A resistor must be connected from the SDA bus line to V DD to act as a pull-up. 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 V DD to act as a pull-up.

NT1GD72S4PA1FU 1GB Registered DDR DIMM AC Timing Specification Notes 1. Input slew rate = 1V/ns. 2. The CK/CK input reference level (for timing reference to CK/CK) is the point at which CK and CK cross: the input reference level for signals other than CK/CK is VREF. 3. Inputs are not recognized as valid until VREF stabilizes. 4. The Output timing reference level, as measured at the timing reference point indicated in AC Characteristics (Note 3) is VTT. 5. tHZ and tLZ transitions occur in the same access time windows as valid data transitions. These parameters are not referred to a specific voltage level, but specify when the device is no longer driving (HZ), or begins driving (LZ). 6. The maximum limit for this parameter is not a device limit. The device operates with a greater value for this parameter, but system performance (bus turnaround) degrades accordingly. 7. The specific requirement is that DQS be valid (high, low, or some point on a valid transition) on or before this CK edge. A valid transition is defined as monotonic and meeting the input slew rate specifications of the device. When no writes were previously in progress on the bus, DQS will be transitioning from Hi-Z to logic LOW. If a previous write was in progress, DQS could be HIGH, LOW, or transitioning from high to low at this time, depending on tDQSS. 8. A maximum of eight Auto refresh commands can be posted to any given DDR SDRAM device. 9. For command/address input slew rate >= 1.0 V/ns. Slew rate is measured between VOH (AC) and VOL (AC). 10. For command/address input slew rate >= 0.5 V/ns and < 1.0 V/ns. Slew rate is measured between VOH (AC) and VOL (AC). 11. CK/CK slew rates are >= 1.0 V/ns. 12. These parameters guarantee device timing, but they are not necessarily tested on each device, and they may be guaranteed by design or tester characterization. 13. For each of the terms in parentheses, if not already an integer, round to the next highest integer. tCK is equal to the actual system clock cycle time. For example, for PC2100 at CL= 2.5, tDAL = (15ns/7.5ns) +(20ns/7.0ns) = 2 + 3 = 5. 14. An input setup and hold time derating table is used to increase tIS and tIH in the case where the input slew rate is below 0.5 V/ns. Input Slew Rate 1. 2. Delta (tIS) Delta (tIH) Unit Note 0.5 V/ns 0 0 ps 1, 2 0.4 V/ns +50 0 ps 1, 2 0.3 V/ns +100 0 ps 1, 2 Input slew rate is based on the lesser of the slew rates determined by either VIH (AC) to VIL (AC) or VIH (DC) to VIL (DC), similarly for rising transitions. These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on each device. 15. An input setup and hold time derating table is used to increase tDS and tDH in the case where the I/O slew rate is below 0.5 V/ns. 1. 2. Input Slew Rate Delta (tDS) Delta (tDH) Unit 0.5 V/ns 0 0 ps 1, 2 0.4 V/ns +75 +75 ps 1, 2 0.3 V/ns +150 +150 ps 1, 2 Note I/O slew rate is based on the lesser of the slew rates determined by either VIH (AC) to VIL (AC) or VIH (DC) to VIL (DC), similarly for rising transitions. These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on each device. 16. An I/O Delta Rise, Fall Derating table is used to increase tDS and tDH in the case where DQ, DM, and DQS slew rates differ. 1. 2. 3. 4. Delta Rise and Fall Rate Delta (tDS) Delta (tDH) Unit Note 0.0 ns/V 0 0 ps 1-4 0.25 ns/V +50 +50 ps 1-4 0.5 ns/V +100 +100 ps 1-4 Input slew rate is based on the lesser of the slew rates determined by either VIH (AC) to VIL (AC) or VIH (DC) to VIL (DC), similarly for rising transitions. Input slew rate is based on the larger of AC to AC delta rise, fall rate and DC to DC delta rise, fall rate. The delta rise, fall rate is calculated as: [1/(slew rate 1)] - [1/(slew rate 2)] For example: slew rate 1 = 0.5 V/ns; slew rate 2 = 0.4 V/ns. Delta rise, fall = (1/0.5) - (1/0.4) [ns/V] = -0.5 ns/V Using the table above, this would result in an increase in tDS and tDH of 100 ps. These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on each device.
