PRELIMINARY*

128MB – 16Mx64 DDR SDRAM UNBUFFERED

FEATURES

DESCRIPTION

ꢀ

Double-data-rate architecture

The W3DG6418S is a 16Mx64 Double Data Rate

SDRAM memory module based on 128Mb DDR SDRAM

components. The module consists of eight 16Mx8 DDR

SDRAMs in 66 pin TSOP package mounted on a 184

Pin FR4 substrate.

ꢀ

DDR200 and DDR266

• JEDEC design speciﬁcations

ꢀ

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.
