Shape-Dependent Reconfigurable Gate Structure in Magnetically Coupled Cellular Automata Logic Device
摘要
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 recon-figurable 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 in-put combinations are obtained .The proposed reconfigurable gate structure lays a solid theoretical foundation for designing pro-grammable magnetic logic computation circuits .关键词
