Description
NT512D64S8HB0G, NT512D64S8HB1G, NT512D64S8HB1GY, NT512D72S8PB0G, NT256D64SH88B0G, NT256D64SH88B1G,
NT256D64SH88B1GY, NT256D72S89B0G and NT128D64SH4B1G are unbuffered 184-Pin Double Data Rate (DDR) Synchronous DRAM
Dual In-Line Memory Modules (DIMM). NT512D64S8HB1GY and NT256D64SH88B1GY are packaged using lead free technology.
NT512D64S8HB0G, NT512D64S8HB1G and NT512D64S8HB1GY are 512MB modules organized as dual ranks using sixteen 32Mx8
TSOP devices. NT512D72S8PB0G has ECC and is organized as dual ranks using eighteen 32Mx8 TSOP devices. NT256D64SH88B0G,
NT256D64SH88B1G and NT256D64SH88B1GY are 256MB modules organized as single rank using eight 32Mx8 TSOP devices.
NT256D72S89B0G has ECC and is organized as single rank using nine 32Mx8 TSOP devices. NT128D64SH4B1G are 128MB modules,
organized as single rank using four 16Mx16 TSOP devices.
Depending on the speed grade, these DIMMs are intended for use in applications operating up to 200 MHz clock speeds and achieves
high-speed data transfer rates of up to 400 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.

Function
The system clock inputs. 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

-
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

-
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.

Supply
Data and Check Bit input/output pins operate in the same manner as on conventional
DRAMs.
Data strobes: Output with read data, input with write data. 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.
Serial EEPROM positive power supply.

1. Inputs are not recognized as valid until VREF stabilizes.
2. VREF is expected to be equal to 0.5 VDDQ of the transmitting device, and to track variations in the DC level of the same. Peak-to-peak
noise on VREF may not exceed 2% of the DC value.
3. VTT is not applied directly to the DIMM. 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.
4. VID is the magnitude of the difference between the input level on CK and the input level on CK.

AC Characteristics
Notes 1-5 apply to the following Tables; Electrical Characteristics and DC Operating Conditions, AC Operating
Conditions, Operating, Standby, and Refresh Currents, and Electrical Characteristics and AC Timing.)
1. All voltages referenced to VSS.
2. 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. Refer to the AC Output Load Circuit below.
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 is 1V/ns in the range between VIL (AC) and VIH (AC) unless otherwise specified.
5. The AC and DC input level specifications are as defined in the SSTL_2 Standard (i.e. the receiver effectively switches as a result of the
signal crossing the AC input level, and remains in that state as long as the signal does not ring back above (below) the DC input LOW
(HIGH) level.

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 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.

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.
