FEATURES

DESCRIPTION

ꢀ

Double-data rate architecture

the W3EG72128S is a 2x64ꢀx72 Double data Rate

SDRAꢀ memory module based on 512ꢀb DDR SDRAꢀ

components. The module consists of eighteen 64ꢀx8

DDR SDRAꢀs in 66 pin TSOP packages mounted on a

184 pin FR4 substrate.

ꢀ

DDR200, DDR266, DDR333 and DDR400

• 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 precisse 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.
