VirtualChannelTM DYNAMIC RAM MODULE  
UNBUFFERED TYPE  
Description  
The MC-45V32AD642 is a 33,554,432 words by 64 bits VirtualChannel dynamic RAM module on which 16 pieces of  
128Mbits VirtualChannel DRAM : µPD45V128821 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.
