Description
The V827464K24S memory module is organized
67,108,864 x 72 bits in a 184 pin memory module.
The 64M x 72 memory module uses 18 Mosel-
Vitelic 32M x 8 DDR SDRAM. The x72 modules are
ideal for use in high performance computer systems
where increased memory density and fast access
times are required.
