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: An integrated semiconductor memory includes memory cells that store a first data record has at least one datum with a first or second data value and a second data record has at least one datum with the first or second data value. The integrated semiconductor memory has a combination circuit that generates the third data record on the output side from the data records fed to the combination circuit on the input side to ascertain based on the third data record whether the first and second data records have been fed to the combination circuit on the input side. The combination circuit generates the datum of the third data record with the first data value, if the first and second data records were fed to the combination circuit on the input side.

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: 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: A circuit for controlling an access to an integrated memory includes a command decoder for receiving at least one external command for an access to the memory. An access controller is connected to the command decoder for receiving internal command signals, which are output by the command decoder. In the course of a memory access, the command decoder outputs a precharge command signal for precharging a row of the memory cell array of the integrated memory. A control circuit, which can determine a temperature of the memory, is designed to temporally variably influence the transmission of the precharge command signal of the command decoder to the access controller in a manner dependent on the temperature of the memory. The write recovery time tWR can be retained even for higher operating frequencies of the memory.
