Description

The MC-4516CB646EF, MC-4516CB646PF and MC-4516CB646XF are 16,777,216 words by 64 bits synchronous dynamic RAM module on which 8 pieces of 128M SDRAM: ?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.
