Memristor-based stateful logic circuits can perform logic operations and logic value storage, which creates an intriguing opportunity for the implementation of an advanced computational architecture. This study proposes a novel memristor-based stateful logic implementation. Specifically, the presented approach is capable of realising two-input or multi-input AND, OR, NAND and NOR operations, and single-input COPY and NOT operations. In each logic gate, non-volatile resistances of memristor are used as input and output states, thus enabling stateful logic operations. Compared with several existing approaches, the proposed method can lead to a multi-functional stateful logic circuit, performing multiple stateful logic operations simultaneously. The effectiveness of the proposed design is demonstrated with the simulation results of MATLAB and SPICE.
