Description
The V82658J04S memory module is organized
8,388,608 x 64 bits in a 184 pin memory module.
The 8M x 64 memory module uses 4 Mosel-Vitelic
8M x 16 DDR SDRAM. The x64 modules are ideal
for use in high performance computer systems
where increased memory density and fast access
times are required.
