Abstract:
1. A nonvolatile storage gate comprising; a nonvolatile storage element; a data interface control unit adjoining the nonvolatile storage element, and receiving a nonvolatile storage control signal for reading-out data from the nonvolatile storage element and writing-in data to the nonvolatile storage element; and a volatile storage element adjoining the nonvolatile storage element, receiving a data input signal and a clock signal, and outputting a data output signal, wherein the data interface control unit comprises a data write-in driver coupled between a logic gate connected in a form of a loop shape in the volatile storage element and the nonvolatile storage element, and wherein the data write-in driver is configured to function as a buffer, wherein the data interface control unit further comprises a pass switch coupled between an output terminal of the data write-in driver and the nonvolatile storage element, the pass switch is turned ON only at the time of the data write-in operation in accordance with the received nonvolatile storage control signal.
