FEATURES

DESCRIPTION

ꢀ

Double-data-rate architecture

The W3EG7264S is a 2x32Mx72 Double Data Rate

SDRAM memory module based on 512Mb DDR SDRAM

components. The module consists of nine 64Mx8 DDR

SDRAMs stacked in 54 pin TSOP packages mounted on

a 200 pin FR4 substrate. This module is structured as 2

Ranks of 64Mx72 DDR SDRAM.

DDR200, DDR266 DDR333

• JEDEC design speciﬁcations

Bi-directional data strobes (DQS)

Differential clock inputs (CK & CK#)

Programmable Read Latency 2,2.5 (clock)

Programmable Burst Length (2,4,8)

Programmable Burst type (sequential & interleave)

Edge aligned data output, center aligned data input

Auto and self refresh

ꢀ

Synchronous design allows precise cycle control with the

use of system clock. Data I/O transactions are possible on

both edges and Burst Lengths allow the same device to be

useful for a variety of high bandwidth, high performance

memory system applications.

Serial presence detect

Dual Rank
