DESCRIPTION:

This document describes Kingston's 256M x 64-bit 2GB (2048MB) DDR2-800 CL5 SDRAM

(Synchronous DRAM) memory module, based on sixteen 128M x 8-bit DDR2 FBGA components.

This module has been tested to run at DDR2 800MHz at latency timing of 5-5-5-15 at 1.85V. The

SPD is programmed to JEDEC standard latency 667Mhz timing of 5-5-5-15 at 1.8V. This 240-pin

DIMM uses gold contact fingers and requires +1.8V. The electrical and mechanical specifications

are as follows:

FEATURES:

Power supply : Vdd: 1.8V ± 0.1V, Vddq: 1.8V ± 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 5 (clock)

Burst Length: 4, 8 (Interleave/nibble sequential)

Programmable Burst type (sequential & interleave)

Timing Reference: 5-5-5-15 at +1.8V / 5-5-5-15 at +1.85V

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 1.180” (30.00mm), double sided component

PERFORMANCE:

Clock Cycle Time (tCK) CL=5 3ns (min.) / 8ns (max.)
