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.
