MOS INTEGRATED CIRCUIT

MC-458CD641LS

8M-WORD BY 64-BIT

SYNCHRONOUS DYNAMIC RAM MODULE (SO DIMM)

Description

The MC-458CD641LS is a 8,388,608 words by 64 bits synchronous dynamic RAM module (Small Outline DIMM) on

which 8 pieces of 64M SDRAM: µPD4564163 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.
