Patent ID: 8236576

Claim:
A magnetic logic element with toroidal magnetic multilayers, comprising: a substrate, toroidal magnetic multilayers, a first conductive metal layer between the substrate and the toroidal magnetic multilayers, and a second conductive metal layer over the toroidal magnetic multilayers, wherein input signal lines (A), (B) and (C) and output signal line (O) are formed in the first conductive metal layer, and input signal lines (A′), (B′) and (C′) and output signal line (O′) are formed in the second conductive metal layer; Wherein, in operation, at least two of the input signal lines (A), (B) and (C), the toroidal magnetic multilayers, and the respective ones of the input signal lines (A′), (B′) and (C′) constitute input electrical current paths, and the output signal line (O), the toroidal magnetic multilayers, and the output signal line (O′) constitute an output electrical current path.
