A circuit supplies a shift pulse to the magnetic body. The shift pulse includes a first pulse and a second pulse and moves a domain wall in the magnetic body along the second direction. The first pulse has a first pulse width. The second pulse has a second pulse width less than the first pulse width. The second pulse is supplied to the magnetic body after the first pulse.
