摘要： A programmable device including a source-drain-gate structure. The device includes two programming electrodes and an antiferromagnetic multiferroic material between the two programming electrodes for switching the spontaneous polarization between a first spontaneous polarization direction and a second spontaneous polarization direction. The programmable device further includes a ferromagnetic material, which is in immediate contact with the multiferroic material. Magnetization of the ferromagnetic material is switchable by a transition between the first switching state and the second switching state of the multiferroic material by an exchange coupling between electronic states of the multiferroic material and the ferromagnetic material. The programmable device also includes means for determining a direction of the magnetization of the ferromagnetic material. A spin valve effect is used for causing an electrical resistance between the source and the drain electrode.

摘要： In accordance with an aspect of the present disclosure, a memory cell (1) or select element is provided. The element includes an ion conductor element (3) formed of a ion conductor material with mobile metal ions, a first electrically conducing electrode (4) in electrical contact with the ion conductor element, and a second electrically conducting electrode (6) in electrical contact with the ion conductor element, so that the memory cell or select element is programmable by applying an electrical voltage between the first electrode and the second electrode that causes the metal ions to be influenced so that an electrical resistance across the ion conductor element is caused to vary, for example because a metallic protrusion (7) is caused to grow or decompose. In contrast to prior art approaches, the ion conductor element has a shape that is asymmetrical with respect to an exchange of the first electrode (4) and the second electrode (6) for each other.

摘要： A programmable magnetoresistive memory cell. The memory cell has a magnetic element that includes a first and a second ferromagnetic layer. The first and second ferromagnetic layers are separated by a non-ferromagnetic and preferably electrically insulating spacer layer. The data bit is read out by measuring the electrical resistance across the magnetic element. The memory cell further includes: a third ferromagnetic layer having a well-defined magnetization direction and a resistance switching material having a carrier density. The carrier density can be altered by causing an ion concentration to become altered by means of an applied electrical voltage signal. Thus, the carrier density can be switched between a first and second state.

摘要： A complementary logic element including first and second transistor elements. The first and second gate electrodes of the two transistor elements are electrically parallel to form a common gate. Both the coupling layers of the first and the second transistor element include a resistance switching material, a conductivity of which may be altered by causing an ion concentration to alter if an electrical voltage signal of an appropriate polarity is applied. The first and second transistor elements also include an ion conductor layer that is capable of accepting ions from the coupling layer and of releasing ions into the coupling layer. The coupling layers and ion conductor layers are such that the application of an electrical signal of a given polarity to the gate enhances the electrical conductivity of the first coupling layer and diminishes the electrical conductivity of the second, or vice versa.
