shows major revised points.
Description
The MC-458CB64ESB and MC-458CB64PSB are 8,388,608 words by 64 bits synchronous dynamic RAM module
(Small Outline DIMM) on which 4 pieces of 128M SDRAM:
μ
PD45128163 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.
