The invention includes a method of forming a magnetoresistive memory device. A trench is formed in an insulative material, and the trench is partially filled with a first magnetic material to narrow the trench. The narrowed trench is at least partially filled with a conductive material. A second magnetic material is formed over the conductive material. A non-magnetic layer is formed over the second magnetic material. A third magnetic material is formed over the non-magnetic layer. The conductive material and the first and second magnetic materials are incorporated into a sense portion of the magnetoresistive memory device. The third magnetic material is incorporated into a reference portion of the magnetoresistive memory device.
