Description
The V43658Y04VATG-75PC memory module is
organized 8,388,608 x 64 bits in a 144 pin
SODIMM. The 8M x 64 memory module uses 4
Mosel-Vitelic 8M x 16 SDRAM. The x64 modules
are ideal for use in high performance computer
systems where increased memory density and fast
access times are required.
