  • Patent number: 12615967
    Abstract: Magnetoelectric magnetic tunnel junction (MEMTJ) logic devices comprise a magnetoelectric switching capacitor coupled to a pair of magnetic tunnel junctions (MTJs) by a conductive layer. The logic state of the MEMTJ is represented by the magnetization orientation of the ferromagnetic layer of the magnetoelectric capacitor, which can be switched through the application of an appropriate input voltage to the MEMTJ. The magnetization orientation of the magnetoelectric capacitor ferromagnetic layer is read out by the MTJs. The conductive layer is positioned between the capacitor and the MTJs. The MTJ ferromagnetic free layers are exchange coupled to the ferromagnetic layer of the magnetoelectric capacitor. The potential of an MTJ free layer is based on a supply voltage applied to the reference layer of the MTJ. The MTJ reference layers have a magnetization orientation that is parallel or antiparallel to the magnetization orientations of the ferromagnetic layer of the magnetoelectric capacitor.
