16 M-WORD BY 64-BIT DDR SYNCHRONOUS DYNAMIC RAM MODULE  
(SO DIMM)  
Description  
The MC-45D16CD641KS is a 16,777,216 words by 64 bits DDR synchronous dynamic RAM module on which 8  
pieces of 128M DDR SDRAM: µPD45D128164 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.
