Description
The V436516S04VA TG-75PC memory module is
organized 16,777,216 x 64 bits in a 168 pin dual in
line memory module (DIMM). The 16M x 64
memory module uses 8 Mosel-Vitelic 16M x 8
SDRAM. The x64 modules are ideal for use in high
performance computer systems where increased
memory densityand fast access times arerequired.
