SYNCHRONOUS DYNAMIC RAM MODULE (SO DIMM)

Description

EThe MC-4516CD642XS is 16,777,216 words by 64 bits synchronous dynamic RAM module (Small Outline DIMM) on

which 8 pieces of 128M SDRAM: µPD45128163 are assembled.

This module provide high density and large quantities of memory in a small space without utilizing the surface-

Omounting technology on the printed circuit board.

Decoupling capacitors are mounted on power supply line for noise reduction.
