DESCRIPTION:

This document describes Kingston's 32M x 64-bit (256MB) DDR2-675 CL4 SDRAM (Synchronous

DRAM) memory module, based on four 32M x 16-bit DDR2 FBGA components. This module has

been tested to run at DDR2 675MHz at low latency timing of 4-4-4-10 at 1.85V. The SPD is

programmed to JEDEC standard latency timing of 4-4-4-12 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 4 (clock)

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

Programmable Burst type (sequential & interleave)

Timing Reference: 4-4-4-10 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), single sided component

PERFORMANCE:

Clock Cycle Time (tCK) CL=4 3.75ns (min.) / 8ns (max.)

Row Cycle Time (tRC) 60ns (min.)
