One embodiment of a nonvolatile latch circuit comprises a latch circuitry configurated to temporarily hold data and comprising a first output terminal, the latch circuitry is coupled to a high voltage source at a first source terminal and to a low voltage source at a second source terminal, and a first nonvolatile memory element configurated to store said data and comprising a low resistance and a high resistance. The first memory element is connected in-series with a first transistor and coupled between the first output terminal and an intermediate voltage source. The resistance of the first memory element is changed by a bidirectional current running between the first output terminal and the intermediate voltage source, wherein an electrical potential of the intermediate voltage source is higher than that of the low voltage source but lower than that of the high voltage source. Other embodiments are described and shown.
