Description
The Hitachi HM514265D Series, HM51S4265D Series are CMOS dynamic RAMs organized 262,144-
word
× 16-bit. HM514265D Series, HM51S4265D 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 HM514265D Series, HM51S4265D Series offer Extended Data Out (EDO) Page
Mode as a high speed access mode. Internal refresh timer enables HM51S4265D Series self refresh
operation. They have the package variations of 40-pin plastic SOJ and standard 44-pin plastic TSOPII.
