MC-4516DA727
Overview
The MC-4516DA727 is a 16,777,216 words by 72 bits synchronous dynamic RAM module on which 9 pieces of 128M SDRAM: µPD45128841 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.
