16M-WORD BY 64-BIT
SYNCHRONOUS DYNAMIC RAM MODULE (SO DIMM)
Description
The MC-4516CD641ES and MC-4516CD641PS are 16,777,216 words by 64 bits synchronous dynamic RAM
module (Small Outline DIMM) on which 8 pieces of 128M SDRAM: µPD45128163 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.

Notes 1. ICC1 depends on output loading and cycle rates. Specified values are obtained with the output open. In
addition to this, ICC1 is measured on condition that addresses are changed only one time during tCK(MIN.).
2. ICC4 depends on output loading and cycle rates. Specified values are obtained with the output open. In
addition to this, ICC4 is measured on condition that addresses are changed only one time during tCK(MIN.).
3. ICC5 is measured on condition that addresses are changed only one time during tCK(MIN.).
