Classification: H03K

Abstract:
A data storage device comprising:a first node, a second node, and a third node; a first precharge means for precharging the first node and the second node to a first supply voltage in response to a clock signal; a first switching means for providing a first discharge path between the first node and the third node in response to an input signal; a second switching means for providing a second discharge path between the second node and the third node in response to a potential at the first node; a second precharge means for precharging an output terminal to the first supply voltage in response to a potential at the second node; a third switching means for providing a third discharge path between the output terminal and the third node in response to the clock signal and the potential of the second node; and a fourth switching means for connecting the first, second, and third discharge paths with a second supply voltage in response to the clock signal.
