16 M-WORD BY 72-BIT SYNCHRONOUS DYNAMIC RAM MODULE

REGISTERED TYPE

Description

The MC-4516DA726 is a 16,777,216 words by 72 bits synchronous dynamic RAM module on which 18 pieces of

64M SDRAM: µPD4564441 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.
