This article presents a majority-logic device, called sttMAJ, based on spin-transfer torque magnetic tunnel junctions (STT-MTJs). sttMAJ devices make it possible to build Boolean and non-Boolean circuits without any transistors. We leverage a physics-based model of sttMAJ device to the design of different highly scalable current-mode logic circuits and neuromorphic-computing/image-processing applications. The functionality of sttMAJ-based circuits is verified using the SPICE circuit simulator. The simulation results reveal that the gate device not only provides a simple and powerful structure (in terms of implementing digital functions and image-processing applications with a small number of devices) but also offers high performance due to its better electrical properties.

一种基于自旋转移扭矩机制的超大规模逻辑器件，用于类脑计算架构

本文介绍了一种基于自旋转移矩磁隧道结 (STT-MTJ) 的多数逻辑器件，称为 sttMAJ。sttMAJ 器件可以在没有任何晶体管的情况下构建布尔电路和非布尔电路。我们利用基于物理的 sttMAJ 设备模型来设计不同的高度可扩展的电流模式逻辑电路和神经形态计算/图像处理应用程序。使用 SPICE 电路模拟器验证基于 sttMAJ 的电路的功能。仿真结果表明，栅极器件不仅提供了简单而强大的结构（就用少量器件实现数字功能和图像处理应用而言），而且由于其更好的电气特性而提供了高性能。
