MC-4564EC726

64 M-WORD BY 72-BIT SYNCHRONOUS DYNAMIC RAM MODULE

REGISTERED TYPE

Description

The MC-4564EC726 is a 67,108,864 words by 72 bits synchronous dynamic RAM module on which 36 pieces of

128 M SDRAM: µPD45128441 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.
