摘要:
A magnetic memory cell is provided. The magnetic memory cell includes at least one fixed magnetic layer and a plurality of free magnetic layers, separated from the at least one fixed magnetic layer by at least one barrier layer. The free magnetic layers include a first free magnetic layer adjacent to the barrier layer, a second free magnetic layer separated from the first free magnetic layer by at least one spacer layer, and a third free magnetic layer separated from the second free magnetic layer by at least one anti-parallel coupling layer. A magnetic moment of the first free magnetic layer is greater than both a magnetic moment of the second free magnetic layer and a magnetic moment of the third free magnetic layer. The magnetic memory cell may be used in conjunction with a magnetic random access memory device.
