A nonvolatile latch circuit that includes a logic circuitry comprising at least an input terminal, a clock terminal, an output terminal, and a nonvolatile memory element. The logic circuitry is electrically coupled to a high voltage source at a first source terminal and to a low voltage source at a second source terminal. The nonvolatile memory element is electrically coupled to the output terminal at a first end and to a intermediate voltage source at a second end. A logic state of the latch circuit responds to an input signal during an active period of a clock signal. A logic state of the nonvolatile memory element is controlled by a bidirectional current running between the first and second ends. 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. |
