A resistive multilayer device (201) employs a first layer (202) comprising a first material that is electrically conducting, a second layer (204) disposed on the first layer, wherein the second layer (204) comprises a second material having a state that is switchable between an antiferromagnetic state and a paramagnetic state by passing current through the second material, a third layer (208) disposed on the second layer (204), and a fourth layer (206) is disposed between the first and third layers, wherein the fourth layer comprising a dielectric material wherein the third layer comprises a third material that is electrically conducting. The second layer has a resistance in the antiferromagnetic state that is different from its resistance in the paramagnetic state, and the state of the second material is retained in an absence of applied power. The resistive multilayer device can be formed as part of a memory cell of a non-volatile memory, wherein information is stored in the memory cell based upon the state of the second material. |
