Abstract
A multi-layer magnetic memory cell is provided, with magnetic end vectors adjacent the ends of the cell pinned in a fixed direction. To pin the magnetic end vectors, a magnetic field is applied to an end of at least one of the layers of magnetic material in the cell to move the magnetic end vectors in the magnetic material at the end of the cell into a fixed direction. Pinning material is then disposed adjacent to the end to maintain the magnetic end vectors in the magnetic material at the end of the cell in the fixed direction.
