PRELIMINARY*
512MB – 2x32Mx64 DDR SDRAM UNBUFFERED, w/PLL
DESCRIPTION
The W3EG6466S is a 2x32Mx64 Double Data Rate
SDRAM memory module based on 512Mb DDR SDRAM
components. The module consists of sixteen 32Mx8
components as eight 64Mx8 stacked DDR SDRAMs
in 66 pin TSOP 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 qualied or characterized and is subject to
change without notice.
