In this paper, two ternary nonvolatile magnetic flip-flops are proposed to provide power gating in ternary systems. The proposed designs sequence ternary data in ternary data paths in their normal function. Furthermore, they can backup and restore the data of a ternary system before and after power gating. The proposed designs rely on assistance from the spin-Hall effect for the data backup operation, which eliminates the incubation delay. This method also needs no extra supply voltages higher than the nominal voltage of the technology. Furthermore, sub-10-nm gate-all-around carbon nanotube field-effect transistors (GAA-CNTFETs) are utilized to design the flip-flops and the required control switches. In the proposed ternary flip-flops, dual flat-band voltages are used for the GAA-CNTFET to determine the required switching thresholds, which is more feasible than the use of different diameters for the nanotubes. It is notable that the contention-free write operation and the disturbance-free read operation of the proposed design enhance its performance and robustness. Monte Carlo simulations certify the correct function and acceptable robustness of the proposed designs in the presence of various process variations.

具有自旋霍尔辅助功能的磁性非易失性触发器，用于三元系统中的功率门控

在本文中，提出了两个三元非易失性磁性触发器来提供三元系统中的功率门控。所提出的设计以其正常功能在三元数据路径中对三元数据进行排序。此外，他们可以在电源门控之前和之后备份和恢复三元系统的数据。提出的设计依靠自旋霍尔效应的辅助来进行数据备份操作，从而消除了孵育延迟。此方法也不需要高于该技术标称电压的额外电源电压。此外，亚10纳米以下的全栅碳纳米管场效应晶体管（GAA-CNTFET）用于设计触发器和所需的控制开关。在建议的三态触发器中，GAA-CNTFET使用了双平带电压来确定所需的开关阈值，这比使用不同直径的纳米管更可行。值得注意的是，所提出的设计的无竞争写入操作和无干扰读取操作增强了其性能和鲁棒性。蒙特卡洛仿真证明了存在各种工艺变化时所提出设计的正确功能和可接受的耐用性。
