DESCRIPTION
The WED3EG7233S is a 2x16Mx72 Double Data Rate SDRAM memory module based on 128Mb DDR SDRAM ponent. The module consists of eighteen 16Mx8 DDR SDRAMs in 66 pin TSOP 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 Lengths allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.
