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

REGISTERED TYPE

EDescription

OThe MC-4532DA726 is a 33,554,432 words by 72 bits synchronous dynamic RAM module on which 18 pieces of

128M 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.
