Description
The MC-4516CD641ES, MC-4516CD641PS and MC-4516CD641XS 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.
