摘要： An integrated circuit includes a circuit component, a first control circuit and a switchable resistance network. An input voltage is fed to the circuit component on the input side. A control signal generated by the first control circuit is fed to the control terminal of the circuit component. With the switchable resistance network, the first resistance or the second resistance is connected between an output terminal of the circuit component and the output terminal of the integrated circuit to generate a voltage drop between the input side and the output terminal of the circuit component. The integrated circuit makes it possible to generate a current at the output terminal of the circuit component in a manner dependent on the control signal and the voltage dropped between the input side and the output terminal of the circuit component. Families of characteristic curves of transistors of an integrated circuit are determined by the integrated circuit.

摘要： An integrated semiconductor memory, which can be operated in a normal operating state and a test operating state, includes a current pulse circuit with an input terminal for applying an input signal. The current pulse circuit is connected to an output terminal via an interconnect for carrying a current. In the test operating state, the current pulse circuit generates at least one first current pulse with a first, predetermined time duration in a first test cycle and at least one second current pulse with a second, unknown time duration in a subsequent second test cycle. In addition to a first current flowing on the interconnect in the normal operating state, a second current flows on the interconnect during the first test cycle and a third current flows during the second test cycle in the test operating state.

摘要： An integrated circuit includes a current generator circuit with a first input terminal for applying a reference voltage and a second input terminal for applying an input voltage, which is generated internally from an externally applied supply voltage by a voltage generator circuit. The current generator circuit is connected to an output terminal via an interconnect. A first current flows on the interconnect in a test operating state of the integrated circuit. The current generator circuit generates a first partial current in a first test cycle of a test operating state and a second partial current in a subsequent second test cycle. The partial currents are each superposed on the first current on the interconnect. Consequently, three currents occur at the output terminal during the test operating state. The internally generated input voltage of the current generator circuit is determined from the three currents and the reference voltage.

摘要： Integrated semiconductor circuits, in particular, dynamic random access memories include a multiplicity of generator circuits for generating internal voltage levels from an externally applied supply voltage. During testing, the internal voltage levels are altered by the output voltage generated at the output of the generator circuit being adapted to an externally applied test voltage. If the test voltage is outside a tolerance range, the semiconductor circuit maybe destroyed. A protection circuit connected in parallel with the generator circuit limits the output voltage.

摘要： An integrated memory contains a memory cell array, which has word lines and bit lines, and a read/write amplifier, which is connected to the bit lines for the assessing and amplifying data signals. A voltage generator circuit generates a voltage supply for application to the read/write amplifier. A potential difference is applied to the read/write amplifier using different supply potentials. The voltage generator circuit increases the potential difference applied to the read/write amplifier for a limited period of time during an assessment and amplification operation of the read/write amplifier. Charge-dependent control is implemented in the voltage generator circuit. An assessment and amplification operation can be carried out at a comparatively high switching speed and a low power consumption is possible.

摘要： In a driver circuit having a plurality of drivers for driving signals in parallel, the drivers are each connected to an input signal line for receiving a respective input signal and to an output signal line for outputting a respective driven output signal. An output signal line of one of the drivers may be connected, via a switch or switching means, to an output signal line of another of the drivers. A control circuit is connected to one of the drivers and is used to drive the switch or switching means in such a manner that the switching means can be activated, for charge equalization, by the control circuit following a driving operation in one of the drivers. A respective associated memory circuit, by which an associated logic circuit for driving one of the switch or switching means is connected to the relevant output signal line, is connected to the respective output signal line. Overall power consumption of the driver circuit can be minimized.
