Abstract
According to one embodiment, a magnetic memory includes: a magnet configured to store data and shift the data from a first area to a second area by domain wall movement caused by a shift operation; an interconnect spaced apart from the magnet and configured to apply a write field to the magnet at a time of a write operation; and a control circuit configured to cause a shift current for shifting the data to flow in the magnet and to cause a write current for generating the write field to flow in the interconnect, wherein the write current includes a first pulse supplied to the interconnect and a second pulse supplied to the interconnect after the first pulse, and a pulse width of the second pulse is smaller than a pulse width of the first pulse.
