A magnetic shift register includes a first supporting layer, a second supporting layer, a first pinning material layer, and at least one magnetic memory track. The first supporting layer has trenches on a first surface extending along a first direction. The second supporting layer is filled in the trenches, wherein the first support layer and the second support layer have at least a portion substantially equal in height. The first pinning material layer is disposed between the first supporting layer and the second supporting layer, wherein a plurality of end surfaces of the first pinning material layer are exposed on the first surface. The magnetic memory track extending along a second direction on the first surface is disposed over the first support layer, the first pinning material layer, and the second support layer, wherein the second direction is not the same or perpendicular to the first direction.
