Neuromorphic device

Abstract

A neuromorphic device includes: first and second element groups, in which each includes magnetic domain wall movement elements, each of which includes magnetic domain wall movement and ferromagnetic layers, and a non-magnetic layer between the magnetic domain wall movement and ferromagnetic layers, a length of the magnetic domain wall movement layer of each of the magnetic domain wall movement elements belonging to the first element group in a longitudinal direction is shorter than a length of the magnetic domain wall movement layer of each of the magnetic domain wall movement elements belonging to the second element group in the longitudinal direction, and a resistance changing rate when a predetermined pulse is input is higher for each of the magnetic domain wall movement elements belonging to the first element group than for each of the magnetic domain wall movement elements belonging to the second element group.
