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

UNBUFFERED TYPE

Description

The MC-45D16CA721 is a 16,777,216 words by 72 bits DDR synchronous dynamic RAM module on which 9 pieces

of 128M DDR SDRAM: µPD45D128842 are assembled.

These modules provide 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.

Features

• 16,777,216 words by 72 bits organization (ECC type)

• Clock frequency
