DESCRIPTION
The W3EG128M72ETSU is a 128Mx72 Double Data Rate SDRAM memory module based on 1Gb DDR SDRAM components. The module consists of nine 128Mx8 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.
