Description
The MC-4532CD646 is a 33,554,432 words by 64 bits synchronous dynamic RAM module on which 16 pieces of
128M SDRAM:
μ
PD45128841 are assembled.
This module provides 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.
