8M-WORD BY 64-BIT

VirtualChannel^TMSYNCHRONOUS DYNAMIC RAM MODULE

UNBUFFERED TYPE

Description

The MC-45V8AB641 is a 8,388,608 words by 64 bits VirtualChannel synchronous dynamic RAM module on which 4

pieces of 128M VirtualChannel SDRAM : µPD45125161 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.
