UNBUFFERED TYPE
Description
The MC-45D32CD641 is a 33,554,432 words by 64 bits DDR synchronous dynamic RAM module on which 16
pieces of 128M DDR SDRAM: µPD45D128842 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.
