Description
The V826632G24S memory module is organized
33,554,432 x 64 bits in a 200 pin memory module.
The 32M x 64 memory module uses 8 Mosel-Vitelic
32M x 8 DDR SDRAM. Th e x64 modu les are ideal
for use in high performance computer systems
where increased memory den sity and fast access
times are required.
