Description
The Hitachi HM51(S)4170D Series, HM51(S)4270D Series are CMOS dynamic RAM organized as
262,144-word
× 16-bit. HM51(S)4170D Series, HM51(S)4270D Series have realized higher density, higher
performance and various functions by employing 0.8
m CMOS process technology and some new CMOS
circuit design technologies. The HM51(S)4170D Series, HM51(S)4270D Series offer fast page mode as a
high speed access mode. They have the package variations of standard 40-pin plastic SOJ and standard 44-
pin plastic TSOPII. Internal refresh timer enables HM51S4170D Series, HM51S4270D Series self refresh
operation.
