HM51W4400B General Description
The Hitachi HM51W4400B is a CMOS dynamic RAM organized 1,048,576-word × 4-bit. HM51W4400B has realized higher density, higher performance and various functions by employing 0.8 mm CMOS process technology and some new CMOS circuit design technologies. The HM51W4400B offers Fast Page Mode as a high speed access mode. Multiplexed address input permits the HM51W4400B to be packaged in standard 300-mil 26-pin plastic SOJ and standard 300-mil 26-pin plastic TSOP II.
