Auto and self refresh Serial presence detect Dual Rank www.DataSheet4U.com DESCRIPTION The W3EG2128M72AFSR is a 2x128Mx72 Double Data Rate SDRAM memory module based on 512Mb DDR SDRAM components. The module consists of thirtysix 128Mx4 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 Lengths allow the same device to be useful for a variety of high bandwidth, high performance memory system applications. * This product is subject to change without notice.
