The HY6264A is a high-speed, low power and 8,192×8-bits CMOS static RAM fabricated using Hyundai’s high performance twin tub CMOS process technology. This high reliability process coupled with innovative circuit design techniques, yields maximum access time of 70ns. The HY6264A has a data retention mode that guarantees data to remain valid at the minimum power supply voltage of 2.0 volt. Using the CMOS technology, supply voltage from 2.0 to 5.5 volt has little effect on supply current in the data retention mode. Reducing the supply voltage to minimize current drain is unnecessary for the HY6264A Series.
