FEATURES

DESCRIPTION

ꢀ

Double-data-rate architecture

The W3EG7234S is a 32Mx72 Double Data Rate

SDRAM memory module based on 128Mb DDR

SDRAM component. The module consists of eighteen

32Mx4 DDR SDRAMs in 66 pin TSOP package

mounted on a 184 Pin FR4 substrate.

Clock speeds: 100MHz and 133MHz

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 Lenths allow the

same device to be useful for a variety of high bandwidth,

high performance memory system applications.
