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.

E
PROM – is assembled onto the module. Informa-
tion about the module configuration, speed, etc. is
written into the E
duction using a serial presence detect protocol (I
synchronous 2-wire bus)
