128MB - 16Mx64 DDR SDRAM UNBUFFERED

DESCRIPTION

The WED3DG6417S is a 16Mx64 Double Data Rate

SDRAM memory module based on 128Mb DDR SDRAM

component. The module consists of eight 16Mx8 DDR

SDRAMs in 66 pin TSOP package mounted on a 200

pin FR4 Substrate.

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.

* This datasheet describes a product that may or may not be under development

and is subject to change or cancellation without notice.
