FEATURES

DESCRIPTION

ꢀ

Double-data-rate architecture

The W3EG64128S is a 2x64Mx64 Double Data Rate

SDRAM memory module based on 512Mb DDR SDRAM

component. The module consists of sixteen 64Mx8 DDR

SDRAMs in 66 pin TSOP packages mounted on a 184

pin FR4 substrate.

ꢀ

Clock speeds of 100MHz, 133MHz, 166MHz and

200MHz

ꢀ

DDR200, DDR266, DDR333 and DDR400

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.
