Description
The V43644R04VCTG-75 memory module is
organized 4,194,304 x 64 bits in a 168 pin dual in
line memory module (DIMM). The 4M x 64 memory
module uses 4 Mosel-Vitelic 4M 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.
