Description
The V827432K24S memory module is organized
33,554,432 x 72 bits in a 184 pin memory module.
The 32M x 72 memory module uses 9 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.
