Multiple-valued logic (MVL) shows considerable advantages over binary logic in certain applications because of the increased informational content of its signals, and hence reduction in interconnects. Flip-flops (FFs) are the basic elements of many systems and are widely used in microprocessors due to their high performance. This article presents two spintronic ternary retention FFs, and a nonvolatile universal ternary shift register (NUTSR) based on gate-all-around carbon nanotube field-effect transistors (GAA-CNTFETs) and nonvolatile magnetic tunnel junction (MTJ). In the proposed input-aware ternary retention FF circuit, power consumption is significantly reduced by adding a magnitude comparator (MC) circuit and preventing duplicate data transfer to MTJs. Simulation results indicate that our design offers at least 22%, 40%, and 15% reductions in power consumption, backup time, and restore energy, respectively. Moreover, it eliminates the risk of data loss in the event of a sudden power outage.

高性能自旋电子非易失性三态触发器和通用移位寄存器

在某些应用中，多值逻辑（MVL）与二进制逻辑相比具有明显的优势，这是因为其信号的信息内容增加，从而减少了互连。触发器（FF）是许多系统的基本元素，由于其高性能而被广泛用于微处理器中。本文介绍了两个自旋电子三元保持FF，以及一个基于全栅碳纳米管场效应晶体管（GAA-CNTFET）和非易失性磁性隧道结（MTJ）的非易失性通用三元移位寄存器（NUTSR）。在提出的输入感知三元保持FF电路中，通过添加幅度比较器（MC）电路并防止重复数据传输到MTJ，可以显着降低功耗。仿真结果表明，我们的设计至少提供22％，40％，和分别减少15％的功耗，备用时间和恢复能源。而且，它消除了在突然断电的情况下数据丢失的风险。
