PRELIMINARY*

1GB – 2x64Mx72 DDR SDRAM REGISTERED w/PLL

FEATURES

DESCRIPTION

ꢀ

Double-data-rate architecture

The W3EG72129S is a 2x64Mx72 Double Data Rate

SDRAM memory module based on 512Mb DDR SDRAM

component. The module consists of eighteen 64Mx8 DDR

SDRAMs in 66 pin TSOP package mounted on a 184 Pin

FR4 substrate.

ꢀ

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

200MHz

ꢀ

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.
