Magnetic logic device and methods of manufacturing and operating the same

摘要

Provided are a magnetic logic device (MLD) and methods of manufacturing and operating the same. The MLD includes: a first interconnection (40); a lower magnetic layer (42a) formed on the first interconnection, the lower magnetic layer having a magnetization direction fixed in a predetermined direction; a non-magnetic layer (42b) formed on the lower magnetic layer; an upper magnetic layer (42c) formed on the non-magnetic layer, the upper magnetic layer having a magnetization direction parallel or anti-parallel to the magnetization direction of the lower magnetic layer; and a second interconnection (44) formed on the upper magnetic layer. A first current source (46) is disposed between one end of the first interconnection and one end of the second interconnection and a second current source (48) is disposed between the other end of the first interconnection and the other end of the second interconnection.
