Patent ID: 8295072

Claim:
An array comprising a plurality of magnetic random access memory (MRAM) cells, each MRAM cell comprising: a device comprising a magnetic flip-flop device comprising: a magnetization controlling structure; a first tunnel barrier structure; and a magnetization controllable structure comprising: a first polarizing layer; and a first stabilizing layer, wherein the first tunnel barrier structure is between the magnetization controllable structure and the magnetization controlling structure and the first polarizing layer is between the first stabilizing layer and the first tunnel barrier structure, wherein the first polarizing layer comprises cobalt (Co), iron (Fe), cobalt iron alloys (CoFe), cobalt iron boron alloys (CoFeB), or combinations thereof, and wherein the first stabilizing layer comprises alloys of gadolinium (Gd), alloys of terbium (Tb), alloys of dysprosium (Dy), alloys of cobalt (Co) and alloys of samarium (Sm); a reference layer; and a second tunnel barrier structure, wherein the second tunnel barrier structure is between the magnetic flip-flop device and the reference layer; and a diode electrically coupled to the MRAM device, wherein the plurality of MRAM devices are connected to each other in an array.
