    摘要: A conductor structure for a magnetic memory is disclosed. The conductor structure includes one or more conductors that have a width that is less than a dimension of a memory cell in a direction the conductor crosses the memory cell. A thickness of the conductor is preselected to reduce a cross-sectional area of the conductor and increase a current density within the conductor. A magnetic field sufficient to rotate an alterable orientation of magnetization in a data layer of the memory cell can be generated by a reduced magnitude of a current flowing in the conductor due to the increased current density. Alternatively, the magnitude of the current can be reduced by increasing a thickness of the conductor to increase its area and reduce its resistance to the flow of electrons and partially cladding the conductor to reduce a total magnetic path around the conductor thereby increasing the magnetic field.
