16M-WORD BY 64-BIT SYNCHRONOUS DYNAMIC RAM MODULE UNBUFFERED TYPE
Description
The MC-4516CB646 is a 16,777,216 words by 64 bits synchronous dynamic RAM module on which 8 pieces of 128M SDRAM: µPD45128841 are assembled. This module provides high density and large quantities of memory in a small space without utilizing the surfacemounting technology on the printed circuit board. Decoupling capacitors are mounted on power supply line for noise reduction.
