Description
The MC-4516DC72 is a 16,777,216 words by 72 bits synchronous dynamic RAM module on which 18 pieces of 64M
SDRAM :
μ
PD4564841 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.
