Description
NT256D64S88AMGM is an unbuffered 200-Pin Double Data Rate (DDR) Synchronous DRAM Dual In-

Line Memory Module (DIMM), organized as a one-bank high-speed memory array. The 32Mx64

module is a single-bank DIMM that uses eight 32Mx8 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-A12 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

200pin DDR SO-DIMMs provide a high-performance, flexible 8-byte interface in a 2.66" long

space-saving footprint.

Functional Description

High Active Low Active Low Function address and control inputs are sampled on the rising

edge of their associated clocks. The negative line of the differential pair of system

clock inputs. Activates the 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 SDRAM command decoder when low and disables the

command decoder when high. When the command decoder is disabled, new commands are ignored

but previous operations continue. 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) A0 - A9 A10/AP

A11, A12 when sampled at the rising clock edge. In addition to the column address, AP is

used to (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 define 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. DQ0 - DQ63, DQS0 - DQS7 (SSTL) (SSTL)

Active High Active High 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. The data write

masks, associated with one data byte. In Write mode, DM operates as a DM0 ­ DM7 Input 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. VDD, VSS SA0 ­ SA2 SDA SCL VDDSPD Supply Supply 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 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. Positive The
