MOS INTEGRATED CIRCUIT  
MC-458CB646  
8M-WORD BY 64-BIT SYNCHRONOUS DYNAMIC RAM MODULE  
UNBUFFERED TYPE  
Description  
The MC-458CB646EFB, MC-458CB646PFB and MC-458CB646XFB are 8,388,608 words by 64 bits synchronous  
dynamic RAM module on which 4 pieces of 128M SDRAM: µPD45128163 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.
