Patent ID: 8809827

Claim:
A thermally assisted magnetoresistive random access memory device (TAS-MRAM), comprising: a magnetic tunnel junction configured to store data; a first multilayer contact structure positioned on one end of the magnetic tunnel junction; and a second multilayer contact structure positioned on an opposite end of the magnetic tunnel junction, such that the first multilayer contact structure and the second multilayer contact structure sandwich the magnetic tunnel junction in between; wherein the first multilayer contract structure is patterned with a width coextensive to a width of the magnetic tunnel junction; wherein the second multilayer contact structure is patterned with a width extended be and the width of the magnetic tunnel junction; wherein the first multilayer contact structure and the second multilayer contact structure each include multiple layers of metals, the multiple layers of metals structured to inhibit thermal conductivity between the magnetic tunnel junction and surrounding structures, and the multiple layers of metals structured to electrically conduct electrical current.
