The nanoscale implementations of ternary logic circuits are particularly attractive because of high information density and operation speed that can be achieved by using emerging memristor technologies. Memristor is a nanoscale device with nonvolatility and adjustable multilevel states, which creates an intriguing opportunity for the implementation of ternary logic operations. This paper proposes a novel memristor-based design for stateful ternary logic, including AND, OR, NOT, NAND, NOR, and COPY operations. In the proposed memristor ternary logic (MTL) design, the resistance of memristor is the only logic state variable for representing the input and output. By sensing the value of the input memristors, the resistance of the output memristor changes accordingly. Furthermore, the MTL gates are not only capable of performing logic operations, but also storing logic values. To illustrate the potential of the methodology, a single-input-three-output ternary decoder is designed by using the proposed ternary logic circuits. Simulation results verify the effectiveness of the presented design.

MTL：忆阻器三元逻辑设计

三元逻辑电路的纳米级实现特别有吸引力，因为可以通过使用新兴忆阻器技术实现高信息密度和操作速度。忆阻器是一种具有非易失性和可调节多级状态的纳米级器件，它为实现三元逻辑运算创造了一个有趣的机会。本文提出了一种新颖的基于忆阻器的有状态三元逻辑设计，包括 AND、OR、NOT、NAND、NOR 和 COPY 操作。在所提出的忆阻器三元逻辑 (MTL) 设计中，忆阻器的电阻是表示输入和输出的唯一逻辑状态变量。通过感测输入忆阻器的值，​​输出忆阻器的阻值会相应变化。此外，MTL 门不仅能够执行逻辑运算，而且还存储逻辑值。为了说明该方法的潜力，使用所提出的三进制逻辑电路设计了一个单输入三输出三进制解码器。仿真结果验证了所提出设计的有效性。
