    Abstract: The invention relates to a label identification system comprised of a transmitting-receiving unit and of identification labels on which the identification information is stored in the form of a digital identification information word. The provision of a circuit on the identification label in the form of a circuit arrangement, which is prefabricated using a polymer technique and on which the identification information is subsequently placed by the offset printing of conductor tracks, enables the provision of an identification label involving a minimal consumption of energy during inexpensive mass production. The bulk of the identification information processing is transferred to the transmitting-receiving unit.

    Abstract: The invention relates to an electronic component that can be operated by means of an alternating voltage. Said component includes at least one input, at least one output and a pair of electronic sub-components with an identical function. The input(s) of the electronic component is/are coupled to a respective input of the electronic sub-components with an identical function and the output(s) of the electronic component is/are coupled to a respective output of said electronic sub-components. In addition, the electronic component is configured in such a way that at least one output only one output signal of the first sub-component of the pair of functionally identical electronic components can be picked up during a first half-wave of an alternating voltage, whereas only one output signal of the second sub-component of the pair of functionally identical electronic can be picked up during the second half-wave of the alternating voltage.

    Abstract: A multivalue magnetoresistive read/write memory and method of writing to and reading from such a memory. The invention has, inter alia, one or more storage cells, each storage cell having two intersecting electric conductors and a layer system comprising magnetic layers located at the intersection of the electric conductors. The memory is characterized in that the layer system is designated as a multilayer system with two or more magnetic layers, wherein at least two of the magnetic layers have a magnetization direction that can be set independently of one another. Further, the magnetization direction of the individual layers may be changed on the basis of the electric current flowing through the electric conductors.

    Abstract: A magnetoresistive memory is described and contains a common word line voltage source, bit lines, word lines crossing the bit lines, and a memory cell array having memory cells with cell resistors. The memory cell array further has reference cells with reference cell resistors. The memory cell array is configured such that for testing a respective cell resistor in each case two of the reference cell resistors nearest the respective cell resistor and the reference cell are simultaneously connected to a common word line voltage. A first feedback amplifier together with the two reference cell resistors form a summing amplifier. A second feedback amplifier together with the respective cell resistor form an amplifier having an equivalent gain as the summing amplifier. A comparator is connected to the summing amplifier and the amplifier. The comparator has an output supplying an evaluation signal dependent on the respective cell resistor.
