W3EG2128M64ETSR-JD3
ADVANCED*
2GB – 2x128Mx64 DDR SDRAM REGISTERED w/PLL
DESCRIPTION
The W3EG2128M64ETSR is a 2x128Mx64 Double Data
Rate SDRAM memory module based on1Gb DDR SDRAM
component. The module consists of sixteen 128Mx8 DDR
SDRAMs in 66 pin TSOP package mounted on a 184 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 product is under development, is not qualied or characterized and is subject to
change or cancellation without notice.
