MC-45V8AB641

DATA SHEET MOS INTEGRATED CIRCUIT MC-45V8AB641 VirtualChannel TM 8M-WORD BY 64-BIT SYNCHRONOUS 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 surfacemounting technology on the printed circuit board. Decoupling capacitors are mounted on power supply line for noise reduction.
