Abstract:
1. A thermally assisted magnetoresistive random access memory device (TAS-MRAM) comprising: a non-magnetic heating structure, wherein the non-magnetic heating structure is formed of a barrier seed layer disposed directly on a buffer layer, a non-magnetic tunnel barrier disposed directly on the barrier seed layer, a barrier cap layer disposed directly on the non-magnetic tunnel barrier, and a top buffer layer disposed directly on the barrier cap layer; an antiferromagnetic layer disposed directly on the top buffer layer of the non-magnetic heating structure; and a magnetic tunnel junction disposed directly on the antiferromagnetic layer, wherein the magnetic tunnel junction includes a ferromagnetic storage layer disposed directly on the antiferromagnetic layer, a non-magnetic active tunnel barrier disposed directly on the ferromagnetic storage layer, and a ferromagnetic sense layer disposed directly on the non-magnetic active tunnel barrier.
