Abstract
A multi-layer magnetic memory cell is provided, with magnetic vectors aligned along a length of the cell. To align the magnetic end vectors, an ellipsoidal shape is formed at the ends of the memory cell. Magnetic vectors aligned along the length prevent from forming high fields and magnetic poles at the discontinuity or ends of the layers. The memory cell with the ellipsoidal shape shows a constant magnetic resistance of the magnetic cell when a magnetic field is applied to the cell and attains a reduction of power consumption for the magnetic cell.
