摘　　要：忆阻器是一种具有阻值开关特性的信息存储器件.由于忆阻器件具有可变电导性,其组合电路可应用与逻辑运算.本文提出了一种新的忆阻器-CMOS逻辑电路,能够在同一电路中同时实现ANDOR-XOR-XNOR 4种基本的逻辑操作.相较于MAD Gates, MRL, IMPLY逻辑电路,忆阻器数量和功耗均有大幅降低,电路性能更优,电路效率大幅提高.在此基础上设计了一种新的全加电路及二值图像加密电路.与现有忆阻器逻辑加法电路相比,本文设计的加法电路在元件数量上同样具有极大的优势.本文设计的二值图像加密电路能够用两种不同的加密方式实现图像加密,密钥与电路相互独立,提高了加密结果的可靠性.Memristors are a kind of information-storage device with resistance-switching dynamics. Due to the variable conductivity of memristive devices, their composite circuits can be used for implementation of logic operations. In this paper, a novel hybrid CMOS-memristor-based logic circuit is proposed for use in realizing four basic logic operations(AND, OR, XOR, XNOR) simultaneously within the same circuit. Compared with existing logic implementations(MAD Gates, MRL, IMPLY), the present circuit offers better performance and greater efficiency, owing to the significant reduction in the number of memristors used in the circuit and the power consumption. Thus, a new full-adder circuit and a binary-image-encryption circuit are designed. Unlike previous full-adder circuits, the proposed one has great advantages in terms of the number of circuit elements. In the proposed encryption circuit, there are two available encryption methods and the encryption key is independent of the circuit, which can improve the reliability of encryption results.
