MOS INTEGRATED CIRCUIT  
MC-4516CD641ES, 4516CD641PS  
16M-WORD BY 64-BIT  
SYNCHRONOUS DYNAMIC RAM MODULE (SO DIMM)  
Description  
The MC-4516CD641ES and MC-4516CD641PS are 16,777,216 words by 64 bits synchronous dynamic RAM  
module (Small Outline DIMM) on which 8 pieces of 128M SDRAM: µPD45128163 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.
