Description
The MC-42S8LFG64S is a 8,388,608 words by 64 bits dynamic RAM module (Small Outline DIMM) on which 8
pieces of 64M DRAM :
μ
PD42S65165 are assembled.
This module provides high density and large quantities of memory in a small space without utilizing the surface-
mounting technology on the printed circuit board.
Decoupling capacitors are mounted on power supply line for noise reduction.
