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.
