Abstract

An information storage device includes a magnetic layer configured to store information, a first and second conductive layer. The first conductive layer contacts a first end of the magnetic layer. The second conductive layer contacts a second end of the magnetic layer. The magnetic layer includes first and second pinning regions at which magnetic domain walls are pinned. The widths of the magnetic layer at the first and second pinning regions are different.
