Description
The MC-458CA725 is an 8,388,608 words by 72 bits synchronous dynamic RAM module on which 9 pieces of 64M
SDRAM :
μ
PD4564841 (Revision E) 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.
