    摘要: Noise-reducing transistor arrangement having first and second field effect transistors (FETs) having source terminals coupled together, drain terminals coupled together, and control terminals for application of a first or second signal. A clock generator unit is configured to provide the first and second signals alternately to the FETs with an alternating frequency which is at least as great as the cut-off frequency of the noise characteristic of the FETs, or with a reciprocal alternating frequency which is less than a mean lifetime of an occupation state of a defect in the boundary region between channel region and gate insulating layer of the FETs. The first signal is applied to the control terminal of the first FET and, simultaneously, the second signal to the control terminal of the second FET. The second signal is applied to the control terminal of the first FET and, simultaneously, the first signal to the control terminal of the second FET.

    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.
