MC-45D32DC721  
32 M-WORD BY 72-BIT DDR SYNCHRONOUS DYNAMIC RAM MODULE  
REGISTERED TYPE  
Description  
The MC-45D32DC721 is a 33,554,432 words by 72 bits DDR synchronous dynamic RAM module on which 18  
pieces of 128M DDR SDRAM: µPD45D128842 are assembled.  
These modules provide 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.
