DESCRIPTION

The WV3EG232M64EFSU is a 2x32Mx64 Double Data

Rate SDRAM memory module based on 256Mb DDR

SDRAM components. The module consists of sixteen

32Mx8 4 banks DDR SDRAMs in FBGA packages

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 Lengths allow the same device to be

useful for a variety of high bandwidth, high performance

memory system applications.

* This product is under development, is not qualiﬁed or characterized and is subject to

change or cancellation without notice.
