DESCRIPTION:

This document describes Kingston's 128M x 64-bit 1GB (1024MB) PC4000 SDRAM (Synchronous

DRAM) CL3 memory module. The components on this module include sixteen 64M x 8-bit (16M x

8-bit x 4 Bank) DDR400 SDRAM in TSOP packages. This module has been tested to run at DDR

500MHz low latency timing of 3-3-3-8-1T at 2.7V. The SPD is programmed to JEDEC standard

latency 400Mhz timing of 3-3-3-8-1T at 2.6V.This 184-pin DIMM uses gold contact fingers and

requires +2.6V. The electrical and mechanical specifications are as follows:

FEATURES:

Power supply : Vdd: 2.6V ± 0.1V, Vddq: 2.6V ± 0.1V

Double-data-rate architecture; two data transfers per clock cycle

Bidirectional data strobe(DQS)

Differential clock inputs(CK and CK)

DLL aligns DQ and DQS transition with CK transition

Programmable Read latency 3 (clock)

Programmable Burst length (2, 4, 8)

Programmable Burst type (sequential & interleave)

Timing Reference: 400MHz 3-3-3-8-1T at +2.6V / 500MHz 3-3-3-8-1T at +2.7V

Edge aligned data output, center aligned data input

Auto & Self refresh, 7.8us refresh interval (8K/64ms refresh)

Serial presence detect with EEPROM

High Performance Heat Spreader

PCB : Height 1.250” (31.75mm), double sided component

PERFORMANCE:
