  • Reconfigurable magnetic logic-circuit array and methods for producing and operating such logic devices
    Patent number: 7825686
    Abstract: The invention relates to a reconfigurable magnetic logic-circuit array having at least two magnetoresistive elements, each composed of at least two magnetic layers, which are separated from one another by an intermediate layer, in each instance, whereby one of the magnetic layers, as a reference layer, does not substantially change its magnetization under the influence of external magnetic fields, and the other magnetic layer, as a free layer, changes its magnetization perceptibly under the influence of external magnetic fields, and having at least one conductor for signal ports, with which conductor, when current is flowing, a first magnetic field can be generated that flips the magnetization of the free layers, and having a device for on-demand generation of a second variable magnetic field, which also influences the magnetoresistive elements.
