MC-4516DA727
16 M-WORD BY 72-BIT SYNCHRONOUS DYNAMIC RAM MODULE
REGISTERED TYPE
Description
The MC-4516DA727 is a 16,777,216 words by 72 bits synchronous dynamic RAM module on which 9 pieces of
128M SDRAM: µPD45128841 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.
Features
• 16,777,216 words by 72 bits organization (ECC type)
