PRELIMINARY*

256MB – 32Mx64 DDR SDRAM UNBUFFERED

FEATURES

DESCRIPTION

ꢀ

DDR200, DDR266 and DDR333

The W3EG6432S is a 32Mx64 Double Data Rate

SDRAM memory module based on 256Mb DDR SDRAM

components. The module consists of eight 32Mx8 DDR

SDRAMs in 66 pin TSOP packages mounted on a 200

pin FR4 substrate.

• JEDEC design speciﬁcations

Double-data-rate architecture

ꢀ

Industrial temperature

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.

* This product is under development, is not qualiﬁed or characterized and is subject to

change without notice.
