MC-4532CD647 General Description
The MC-4532CD647EF and MC-4532CD647PF are 33,554,432 words by 64 bits synchronous dynamic RAM module on which 16 pieces of 128M SDRAM: mPD45128841 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.
Decoupling capacitors are mounted on power supply line for noise reduction.
