Abstract:
An apparatus has a reference magnetic tunnel junction with a high aspect ratio including a reference layer with magnetization along a minor axis and a storage layer with magnetization along a major axis. The storage layer magnetization is substantially perpendicular to the magnetization along the minor axis. The magnetization orientation between the minor axis and the major axis is maintained by shape anisotropy caused by the high aspect ratio.
