Abstract
The disclosure is a method of controlling operations in a static random access memory employing twin cells. After a wordline coupled to first and second cell transistors is conductive, a voltage difference between a first bitline, which is connected to a first cell capacitor through the first cell transistor, and a second bitline, which is connected to a second cell capacitor through the second cell transistor, is driven into a sense amplifier to be developed with amplification. An active wordline turns nonconductive when one of the bitline voltages accords with a predetermined reference voltage.
