非易失性磁振子逻辑电路工程

Non-Volatile Magnonic Logic Circuits Engineering

Alexander Khitun, Kang L. Wang

摘要:

我们提出了磁逻辑电路工程的概念,它利用磁化作为计算状态变量,利用自旋波进行信息传输。电路由通过自旋波总线连接的磁电电池组成。我们提出的数值模拟的结果显示的磁电电池开关的自旋波的振幅以及相位的函数。相位相关开关使得可以通过利用自旋波总线作为无源逻辑元件来设计逻辑门,从而向传播的自旋波提供一定的相移。我们提出了一个图书馆的逻辑门组成的磁电细胞和自旋波总线提供0或p相移。除了幅度之外,相位的利用是一个强大的工具,它使我们能够用比CMOS技术所需的更少的元件来构造逻辑电路。作为一个例子,我们提出了一个只包括5个磁电单元的磁振子全加法器电路的设计。所提出的概念可以提供一条路线,以更多的功能波为基础的逻辑电路的能力远远超出了传统的基于晶体管的方法的限制。

英文摘要:

We propose a concept of magnetic logic circuits engineering, which takes an advantage of magnetization as a computational state variable and exploits spin waves for information transmission. The circuits consist of magneto-electric cells connected via spin wave buses. We present the result of numerical modeling showing the magneto-electric cell switching as a function of the amplitude as well as the phase of the spin wave. The phase-dependent switching makes it possible to engineer logic gates by exploiting spin wave buses as passive logic elements providing a certain phase-shift to the propagating spin waves. We present a library of logic gates consisting of magneto-electric cells and spin wave buses providing 0 or p phase shifts. The utilization of phases in addition to amplitudes is a powerful tool which let us construct logic circuits with a fewer number of elements than required for CMOS technology. As an example, we present the design of the magnonic Full Adder Circuit comprising only 5 magneto-electric cells. The proposed concept may provide a route to more functional wave-based logic circuitry with capabilities far beyond the limits of the traditional transistor-based approach.
