Complementary Magnetic Tunnel Junction Logic

This brief proposes and analyzes a novel logic family composed solely of magnetic tunnel junctions (MTJs) to form complimentary pull-up and pull-down networks. This logic family solves the challenge of direct cascading in spintronic logic circuits while also providing non-volatile data storage. The increased logic density possible with complementary MTJs coupled with a charge pulse switching mechanism driven by ferromagnet polarization permits highly efficient logical computation. Furthermore, the presence of non-volatile memory within the logic structure provides a feasible hardware for non-von Neumann computer architectures.
