May 7, 2015 – Majority logic gate for 3D nano-scale magnetic computing

Irina Eichwald et al. demonstrated the potential of 3D high integration density digital computing based on physically field interacting nanometer-scaled magnets with a bistable magnetization state, representing the Boolean logic states ‘0’ and ‘1’, arranged in a 3D manner.

Schematic of a 3D NML logic system. Logic computing is performed by 3D NAND/NOR gates. Information between functional layers is transmitted by magnetic vias, enabling magnetic signal crossing and computing on a multi-level regime. Electrical in and output sensors enable us to transform magnetic information into the electrical domain and vice versa.
