General Description

The MC-458CB64ESB and MC-458CB64PSB are 8,388,608 words by 64 bits synchronous dynamic RAM module (Small Outline DIMM) on which 4 pieces of 128M SDRAM: µPD45128163 are assembled.

These modules provide high density and large quantities of memory in a small space without utilizing the surfacemounting technology on the printed circuit board.

Decoupling capacitors are mounted on power supply line for noise reduction.
