Revision A1
1. GENERAL DESCRIPTION
The W9451GBDA is a 512MB Double Data Rate Synchronous Dynamic RAM (DDR SDRAM) memory
modules. It 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
timing parameters and other necessary information to optimize system setting and maximize its
performance.
