Abstract:
A conductive line for programming a magnetoresistive memory device comprising:an electrically conductive interconnect region positioned proximate to a magnetoresistive random access memory device and wherein the interconnect region is formed within a substrate, wherein the interconnect region is capable of conducting a current for producing a magnetic field and wherein the interconnect region includes a conductive layer with a thickness and a width and has a first side, a second side, a third side, and a fourth side; a ferromagnetic cladding region with a thickness positioned on the first side, the second side, the third side, and the fourth side of the conductive layer; and the ferromagnetic cladding region positioned on the first side defining a trench having a width less than the width of the conductive layer and a depth approximately equal to the thickness of the ferromagnetic cladding region.
