Description

The W9451GBDA is a 512MB Double Data Rate Synchronous Dynamic RAM (DDR SDRAM) memory modules. W9451GBDA is organized in a 64M x 64 bit configuration using eight pieces of Winbond W942508AH (32M x 8 bits) DDR SDRAMs and assembled on a JEDEC standard 184-pin DIMM PCB.

To provide high data bandwidth, W9451GBDA uses a double data rate architecture to transfer two data words per clock cycle and delivers a data bandwidth of up to 2.7G (DDR333) bytes per second. It is ideal for high performance systems that require fast data transfer memory modules.

By reading the Serial Presence-Detect (SPD), the system can identify the module type, DDR SDRAM W9451GBDA timing parameters and other necessary information to optimize system setting and maximize its performance.
