    摘要: 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.

    摘要: Sensor elements are arranged in a hexagonal grid. A processor element in the form of a primitive automaton is assigned to each of the sensor elements in the grid. The processor elements are set up to perform algorithms which enable lines of a fingerprint to be simplified such that characteristic minutiae of the fingerprint (endings and branchings of the lines) can be extracted. The processor elements are embodied using CMOS/Neuron MOS threshold value logic or using CMOS/NMOS pass transistor logic. The image grid can be read out via read-out circuits as a matrix.

    摘要: 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.

    摘要: In an arrangement for signal transmission between chip layers of a vertically integrated circuit, a defined, inductive signal transmission ensues between a part of the vertically integrated circuit in one chip layer and a further part of the vertically integrated circuit in a further chip layer by means of a coupling inductance formed by respective coils in the two layers. Particularly given high connection densities, a large number of freely placeable and reliable vertical signal connections can be produced directly from the inside of one chip layer to the inside of a neighboring chip layer without extremely high demands being made on the adjustment of the chip layers relative to one another and on the surface planarity of the individual chip layers.

The control circuit also has a second pole, which supplies power to an evaluator, and has a third pole that is connected to a reference voltage source. The readout circuit additionally includes a third voltage source having a voltage, which is approximately equal to the voltage of the first reading voltage source and which can be individually connected to second ends of the bit lines by means of switching elements. Finally, the readout circuit includes a fourth voltage source, which can be individually connected to second ends of the word lines by means of switching elements.

    摘要: A description is given of a method and a circuit configuration for evaluating an information content of a memory cell, preferably of an MRAM memory cell, or of a memory cell array. In order to be able to perform accurate and reliable evaluation of the memory cell, a first current value flowing through the memory cell or a voltage value correlated with the current value is measured and conducted through a first circuit branch, which has a switch and a capacitance, and is buffer-stored. The memory cell is subsequently subjected to a programming operation. Afterward, in the same memory cell a second current value or voltage value is measured and conducted through a second circuit branch that has a switch and a capacitance and is buffer-stored there. The two measured values are compared with one another in an evaluation unit.

    摘要: A magneto resistive memory contains first switches, a word line voltage source generating a word line voltage connected to the first switches, a line node, second switches, and cells formed of cell resistors each having a first terminal connected to the word line voltage through one of the first switches and a second terminal connected to the line node through one of the second switches. A reference resistor is connected to the line node and a reference voltage source is connected to the reference resistor. The reference resistor with the reference voltage source brings about a reduction in a respective cell current, flowing from the line node, by an average current. A device is connected to the line node and evaluates the cell resistors. The device has an amplifier for converting a difference between the respective cell current and the average current into a voltage functioning as an evaluation signal.
