Abstract
According to one embodiment, a magnetic memory includes a magnetic body with two portions of a first dimension in a first direction which are spaced from each other a second direction and another portion that has a second dimension less than the first dimension in the first direction, which is between the two other portions. 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.
