VirtualChannelTM SYNCHRONOUS DYNAMIC RAM MODULE  
UNBUFFERED TYPE  
Description  
The MC-45V16AD641 is a 16,777,216 words by 64 bits VirtualChannel synchronous dynamic RAM module on  
which 16 pieces of 64M VirtualChannel SDRAM : µPD4565821 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.
