Zusammenfassung:A spin-based neuron circuit according to the present embodiment includes a domain wall magnet including a domain wall, a spin-based neuron element including a magnetic tunnel junction and having electrical resistance changed by the magnetic domain wall that accumulates an input signal to move in one direction; a differential amplifier outputting a voltage corresponding to the electrical resistance when the spin-based neuron device is expressed. The electrical resistance of the expressed spin-based neuron device is reset. It is possible to provide spin-based neuron circuitry for high integration and low-power operation. 본 실시예에 의한 스핀 기반 뉴런 회로는 자구벽(domain wall)을 포함하는 자구벽 자석(domain wall magnet)과, 자기터널 접합을 포함하며, 입력 신호를 축적하여 일 방향으로 움직이는 자구벽에 의하여 전기 저항이 변화하는 스핀 기반 뉴런 소자 및 스핀 기반 뉴런 소자 발현시 전기 저항에 상응하는 전압을 출력하는 차동 증폭기를 포함하며, 발현된 스핀 기반 뉴런 소자는 전기 저항이 리셋된다.
