Claim 14:
15. A method of manufacturing a bottom-pinned spin-orbit torque magnetic random access memory, comprising:
providing a substrate;
forming a bottom electrode layer, a pinned layer, a reference layer, a free layer, a spin-orbit torque layer, a capping layer and a metal oxide layer sequentially on said substrate;
performing a photolithography process to pattern said bottom electrode layer, said pinned layer, said reference layer, said free layer, said spin-orbit torque layer, said capping layer and said metal oxide layer into a memory unit;
forming an injection layer on said metal oxide layer, wherein a part of said injection layer is directly connected with said metal oxide layer; and
performing an annealing process to make oxygen atoms in said metal oxide layer into said injection layer, thereby oxidizing said part of said injection layer directly connected with said metal oxide layer into a blocking layer.
