Original Abstract Submitted
The present disclosure generally relate to an integrated circuit utilizing spin orbital-spin orbital (SO-SO) logic. The integrated circuit comprises a plurality of SO-SO logic cells, where each SO-SO logic cell comprises a first spin orbit torque (SOT) layer, a second spin orbit torque (SOT) layer, and a ferromagnetic layer disposed between the SOT and SOT layer. Each SO-SO logic cell is configured for: a first current path that is in plane to a plane of the SOT layer, and a second current path that is perpendicular to a plane of the SOT layer, the second current path being configured to extend into the ferromagnetic layer. The integrated circuit further comprises a common voltage source connected to each SOT device, and one or more interconnects disposed between adjacent SOT devices of the plurality of SOT devices, the one or more interconnects connecting the adjacent SOT devices together.
