PRELIMINARY* 512MB – 2x32Mx64 DDR SDRAM UNBUFFERED, w/PLL DESCRIPTION The W3EG6466S is a 2x32Mx64 Double Data Rate SDRAM memory module based on 512Mb DDR SDRAM components. The module consists of sixteen 32Mx8 components as eight 64Mx8 stacked DDR SDRAMs in 66 pin TSOP packages mounted on a 200 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 under development, is not qualified or characterized and is subject to change without notice.
