MC-4532CD646
Overview
The MC-4532CD646 is a 33,554,432 words by 64 bits synchronous dynamic RAM module on which 16 pieces of 128M SDRAM: µPD45128841 are assembled. This module provides high density and large quantities of memory in a small space without utilizing the surfacemounting technology on the printed circuit board.
