Abstract
Provided is a non-volatile latch, which includes a latch circuit, a first switch circuit, a non-volatile memory device, a second switch circuit and a third switch circuit. A first terminal of the first switch circuit is coupled to a first output terminal of the latch circuit. The first switch circuit is turned off in a normal operation period. A first terminal of the non-volatile memory device is coupled to a second terminal of the first switch circuit. A second terminal of the non-volatile memory device is coupled to a programming voltage via the second switch circuit. In a store period, according to latched data of the latch circuit and a state transformation condition of the non-volatile memory device, the third switch circuit can dynamically determine whether to couple the first terminal of the non-volatile memory device to a reference voltage.
