1GB – 2x64Mx72 DDR SDRAM REGISTERED ECC w/PLL

FEATURES

DESCRIPTION

The W3EG72125S is a 2x64Mx72 Double Data Rate

SDRAM memory module based on 256Mb DDR SDRAM

components. The module consists of eighteen 2x64Mx4

stacked (36 components), in 66 pin TSOP package

mounted on a 184 pin FR4 substrate.

ꢀ

Double-data-rate architecture

Clock Speeds of 100MHz, 133MHz and 166MHz

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.
