DESCRIPTION
The WV3EG128M72EFSR is a 128Mx72 Double Data Rate SDRAM memory module based on 512Mb DDR SDRAM ponent. The module consists of eighteen 64Mx8 DDR ponents 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.
