Description

The MC-4516DA726 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 surface mounting technology on the printed circuit board.

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