Abstract
A method and system for providing a magnetic tunneling junction is disclosed. The method and system includes providing a free layer, a pinned layer, and a barrier between the free layer and the pinned layer. The free layer and the pinned layer are ferromagnetic. The barrier layer is an insulator. The magnetic tunneling junction is coupled to a bit line. The bit line includes a ferromagnetic liner and a nonmagnetic core. The nonmagnetic core includes a top, a bottom and sides. The ferromagnetic liner includes at least one tab and is adjacent to the sides and a portion of the bottom of the nonmagnetic core. The at least one tab is adjacent to the portion of the bottom of the nonmagnetic core.
