Description
NT128D64S88A0G is an unbuffered 184-Pin Double Data Rate (DDR) Synchronous DRAM Dual In-Line Memory Module (DIMM),
organized as a one-bank high-speed memory array. The 16Mx64 module is a single-bank DIMM that uses eight 16Mx8 DDR
SDRAMs in 400 mil TSOP packages. The DIMM achieves high-speed data transfer rates of up to 266MHz. The DIMM is intended for use
in applications operating from 100 MHz to 133 MHz clock speeds with data rates of 200 to 266 MHz. Clock enable CKE0 controls all
devices on the DIMM.
Prior to any access operation, the device CAS latency and burst type/ length/operation type must be programmed into the DIMM by
address inputs A0-A11 and I/O inputs BA0 and BA1 using the mode register set cycle.
These DIMMs are manufactured using raw cards developed for broad industry use as reference designs. The use of these common
design files minimizes electrical variation between suppliers.
The DIMM uses serial presence detects implemented via a serial EEPROM using the two-pin IIC protocol. The first 128 bytes of serial PD
data are programmed and locked during module assembly. The last 128 bytes are available to the customer.
All NANYA 184 DDR SDRAM DIMMs provide a high-performance, flexible 8-byte interface in a 5.25” long space-saving footprint.

Supply
During a Bank Activate command cycle, A0-A11 defines the row address (RA0-RA11)
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 Autoprecharge operation at the end of the Burst Read or Write cycle. If AP is high,
autoprecharge is selected and BA0/BA1 define the bank to be precharged. If AP is low,
autoprecharge 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.
Data and Check Bit input/output pins operate in the same manner as on conventional
DRAMs.
Active Data strobes: Output with read data, input with write data. Edge aligned with read data,
High centered on write data. Used to capture write data.
SA0 – SA2
V DDSPD
Selects which SDRAM bank is to be active.
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 bidirectional 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 pullup.
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 pullup.
Serial EEPROM positive power supply.

1. Inputs are not recognized as valid until V REF stabilizes.
2. V REF is expected to be equal to 0.5 V DDQ of the transmitting device, and to track variations in the DC level of the same. Peak-to-peak
noise on V REF may not exceed 2% of the DC value.
3. V TT is not applied directly to the DIMM. V TT is a system supply for signal termination resistors, is expected to be set equal to V REF ,
and must track variations in the DC level of V REF .
4. V ID 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 V SS .
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 I DD tests may use a V IL to V IH swing of up to 1.5V in the test environment, but input timing is still referenced to V REF
(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 V IL(AC) and V IH(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.

PC2100 / PC1600 Unbuffered 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. t HZ and t LZ 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 t DQSS .
8. A maximum of eight Auto refresh commands can be posted to any given DDR SDRAM device.
9. QFC is enabled as soon as possible after the rising CK edge that registers the Write command.
10. QFC is disabled as soon as possible after the last valid DQS edge transitions Low.
11. For command/address input slew rate >= 1.0 V/ns. Slew rate is measured between VOH (AC) and VOL(AC).
12. 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).
13. CK/ CK slew rates are >= 1.0 V/ns.
14. These parameters guarantee device timing, but they are not necessarily tested on each device, and they may be guaranteed by
design or tester characterization.
15. The specified timing is guaranteed assuming QFC is connected to a test load consisting of 20 pF to ground and a pull up resistor of
150 ohms to Vddq .
16. For each of the terms in parentheses, if not already an integer, round to the next highest integer. t CK is equal to the actual system
clock cycle time. For example, for PC2100 at CL = 2.5, t DAL = (15ns/7.5ns) +(20ns/7.0ns) = 2 + 3 = 5.
17. An input setup and hold time derating table is used to increase t IS and t IH in the case where the input slew rate is below 0.5 V/ns.

for rising transitions.
2. These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on eachdevice.
18. An input setup and hold time derating table is used to increase t DS and t DH in the case where the I/O slew rate is below 0.5 V/ns.

1. Input slew rate is based on the lesser of the slew rates determined by either V IH (AC) to V IL (AC) or V IH (DC) to V IL (DC) , similarly
for rising transitions.
2. Input slew rate is based on the larger of AC to AC delta rise, fall rate and DC to DC delta rise, fall rate.
3. 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 t DS and t DH of 100 ps.
4. These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on each
device.

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 V REF.
3. Inputs are not recognized as valid until V REF stabilizes.
4. The Output timing reference level, as measured at the timing reference point indicated in AC Characteristics (Note 3) is V TT .
5. tHZ and t LZ 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).
