摘要

The present invention provides a domain wall movement memory device and an operating method therefor. The device comprises: an information storage pattern which extends in a first direction and which has a domain wall magnetised in the first direction; and a plurality of drive patterns extending in a second direction transverse to the first direction. The information storage pattern comprises a domain wall and magnetic domains, and the drive patterns can move the domain wall of the information storage pattern within the information storage pattern.
