FEATURES

DESCRIPTION

ꢀ

DDR200, DDR266 and DDR333

The W3EG6433S is a 32Mx64 Double Data Rate

SDRAM memory module based on 256Mb DDR

SDRAM component. The module consists of eight

32Mx8 DDR SDRAMs in 66 pin TSOP package

mounted on a 200 Pin FR4 substrate.

Double-data-rate architecture

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.
