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.

用于多功能逻辑电路的基于忆阻器的状态逻辑门

基于忆阻器的状态逻辑电路可以执行逻辑运算和逻辑值存储，这为实现高级计算体系结构创造了诱人的机会。这项研究提出了一种新颖的基于忆阻器的状态逻辑实现。具体而言，所提出的方法能够实现两输入或多输入的“与”，“或”，“与非”和“或非”运算以及单输入COPY和“非”运算。在每个逻辑门中，忆阻器的非易失性电阻都用作输入和输出状态，从而实现有状态逻辑操作。与几种现有方法相比，所提出的方法可以导致多功能状态逻辑电路，同时执行多个状态逻辑运算。MATLAB和SPICE的仿真结果证明了所提出设计的有效性。
