WV3EG128M72EFSR-D3
1GB – 128Mx72 DDR SDRAM REGISTERED w/PLL, FBGA
DESCRIPTION
The WV3EG128M72EFSR is a 128Mx72 Double Data
Rate SDRAM memory module based on 512Mb DDR
SDRAM component. The module consists of eighteen
64Mx8 DDR components in FBGA packages 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 qualified or characterized and is subject to
change or cancellation without notice.
