摘要

磁耦合元胞自动机逻辑器件(即纳磁体逻辑器件)是后CMOS时代的一种极具潜力的新技术,具有无引线集成、极低功耗和天然非易失性等优点.纳磁体逻辑器件由纳米级单畴磁体构成,而磁体的形状是其一个重要的器件特征参数.本文研究了不同特殊形状纳磁体的转换特性,获得了改变特殊形状器件状态的时钟场值.提出了基于不同尺寸特殊形状纳磁体的可重配置择多逻辑门,采用OOMMF软件验证了形状择多逻辑门的输入可重配置性,得到了顺序配置不同输入组合所需的时钟场.该可重配置门结构的提出为磁性可编程逻辑计算电路的实现奠定了重要的理论基础.

Abstract

As one of promising emerging technologies beyond CMOS,magnetically coupled cellular automata logic device (namely nanomagnet logic device) has the advantages of non-down-lead integration,nonvolatility and ultra low power dissipation.Nanomagnet logic device is comprised of single domain magnets,in which shape of the nanomagnet behaves as an important device characteristic parameter.In this paper,switching behavior of different nanomagnets of peculiar shape is deeply investigated,and the required clocking field to flip the logic states of each nanomagnet of peculiar shape is achieved.According to this finding,a reconfigurable majority logic gate based on nanomagnets of peculiar shape of different sizes is proposed.The OOMMF tool is employed to verify inputs reconfigurability of proposed shape-based gate,and the clocking fields required to sequentially reconfigure different input combinations are obtained.The proposed reconfigurable gate structure lays a solid theoretical foundation for designing programmable magnetic logic computation circuits.
