Abstract
A nonvolatile full adder circuit comprising a full adder electrical circuitry comprising three input terminals for receiving two input and carry-in signals, a sum output terminal, and an carry-out output terminal; first and second nonvolatile memory elements electrically coupled to the first and second output terminal, respectively at their first ends and to an intermediate voltage source at their second ends. The nonvolatile memory elements comprise two stable logic states. A logic state each of the of the nonvolatile memory elements is controlled by a bidirectional electrical current running between its first and second ends. The full adder circuitry is electrically coupled to a high voltage source at its first source terminal and to a low voltage source at its second source terminal, wherein an electrical potential of the intermediate voltage source is lower than that of the high voltage source but higher than that of the low voltage source.
