ABSTRACT:
A register having a track with a first electrode is at the first end to supply a current to the track in a first direction and a second electrode at the second end to supply a current to the track in a second direction, the second direction being opposite to the first direction. A first domain wall anchor and a second domain wall anchor are positioned proximate the track between the first electrode and the second electrode. Each of the domain wall anchors has a ferromagnetic pinned layer and a barrier layer proximate the track, with the barrier layer between the track and the ferromagnetic pinned layer. The ferromagnetic layer has a magnetization orientation pinned perpendicular to the magnetization orientation of the track.
