2results about "Logic circuits using saturable magnetic devices" patented technology

A system and method for a logic device is disclosed. A first substrate, a second substrate and a third substrate is provided. A first input nanomagnet is disposed over the first substrate, a second input nanomagnet is disposed over the second substrate, and a third input nanomagnet is disposed over the third substrate. The easy axis of the first input nanomagnet, the second input nanomagnet, and the third input nanomagnet are in a first direction perpendicular to the first substrate, the second substrate and the third substrate. A spacer layer is disposed over the first input nanomagnet, the second input nanomagnet, and the third input nanomagnet. A first ferromagnetic layer is disposed over the spacer layer.

A method for skyrmion based processing is provided. The method comprises generating a number of skyrmions. The skyrmions are moved down a skyrmion racetrack using a multi-phase voltage-controlled magnetic anisotropy (VCMA) clock. A number of logical operations are performed with zero or more skyrmions belonging to the same clock cycle that meet at a logical junction. Outputs of the logical operations fan out to other logic gates for computation of any arbitrary combinatorial function.
