Abstract
A magnetoresistive random access memory and a method for manufacturing the same are provided, with which a stress layer covers a part of the protective layer along a direction of a current in the spin-orbit coupling layer, so that a stress is generated on the part of the magnetic layer locally due to the stress layer, thus a lateral asymmetric structure is formed in a direction perpendicular to the current source. In a case that a current is supplied to the spin-orbit coupling layer, the spin-orbit coupling effect in the magnetic layer is asymmetric due to the stress on the part of the magnetic layer, thereby realizing a deterministic switching of the magnetic moment under the function of the stress.
