Description

The Hitachi HM51(S)4260C is CMOS dynamic RAM organized as 262,144-word

脳

16-bit. HM51(S)4260C

has realized higher density, higher performance and various functions by employing 0.8

碌m

CMOS process

technology and some new CMOS circuit design technologies. The HM51(S)4260C offers fast page mode as a

high speed access mode. Multiplexed address input permits the HM51(S)4260C to be packaged in standard

400-mil 40-pin plastic SOJ and standard 400-mil 44-pin plastic TSOPII. Internal refresh timer enables

HM51S4260C self refresh operation.
