Description
The V826664K24S memory module is organized
67,108,864 x 64 bits in a 184 pin memory module.
The 64M x 64 memory module uses 16 Mosel-
Vitelic 32M x 8 DDR SDRAM. The x64 modules are
ideal for use in high performance computer systems
where increased memory density and fast access
times are required.
