shows major revised points.
Description
The MC-458CB64S is a 8,388,608 words by 64 bits synchronous dynamic RAM module (Small Outline DIMM) on
which 8 pieces of 64 M SDRAM :
μ
PD4564841 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.
