Abstract:
An electronic synapse is disclosed, comprising a heavy metal layer having a high spin orbit coupling, a domain wall magnet layer having a bottom surface adjacent to a top surface of the heavy metal layer, the domain wall magnet layer having a perpendicular magnetic anisotropy, the domain wall magnet layer having a domain wall, the domain wall running parallel to a longitudinal axis of the domain wall magnet layer, a pinned layer having perpendicular magnetic anisotropy, and an oxide tunnel barrier connected between the domain wall magnet layer and the pinned layer, wherein the pinned layer, the oxide tunnel barrier, and the free layer form a magnetic tunnel junction.
