16 M-WORD BY 64-BIT
SYNCHRONOUS DYNAMIC RAM MODULE (SO DIMM)
Description
The MC-4516CD64ES and MC-4516CD64PS are 16,777,216 words by 64 bits synchronous dynamic RAM module
(Small Outline DIMM) on which 8 pieces of 128 M 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.
