Description

The MC-4516CB64PS are 16,777,216 words by 64 bits synchronous dynamic RAM module (Small Outline DIMM) on which 8 pieces of 128 M SDRAM: µPD45128841 are assembled.

These modules MC-4516CB64PS 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 of MC-4516CB64PS are mounted on power supply line for noise reduction.
