Claim Text:
1. A structure for a magnetic random access memory cell comprising: a free layer of a first length; an insulator layer next to the free layer; a pinned layer comprising a first region, a second region, and a third region, wherein the second region is next to the insulator layer and adjacent to the first region and the third region, the second region is of the first length and of a first thickness, and the first region and the third region are of a second length and of a second thickness smaller than the first thickness, wherein: an anti-ferromagnetic material (AFM) layer located next to the pinned layer, the AFM layer having a third length larger than the first length; and a first electrode connected to the free layer and a second electrode in physical contact with the AFM layer, wherein a lateral extent of the second electrode is smaller than a lateral extent of the AFM layer but greater than a lateral extent of the free layer, and wherein a lateral extent of the first electrode is smaller than the lateral extent of the free layer.
