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: A current measurement circuit and method for testing a semiconductor device is provided. The method includes the steps of providing a semiconductor integrated circuit device including a voltage regulating circuit, the voltage regulating circuit being activated as needed to maintain a required voltage level; monitoring the voltage regulating circuit to determine a number of times it is activated during a sample period; and comparing the number of activations to a predetermined limit whereby if the number of activations exceeds the predetermined limit the semiconductor device is defective. The current measurement circuit includes an external clock for providing a clock signal; a first counter for counting when the voltage regulating circuit is activated; a second counter for counting clock cycles of a sample period; and a register for storing the number of activations, wherein the number of activations represents a relative current consumption value of the semiconductor device.

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 semiconductor memory includes a memory cell array in which first sense amplifiers are arranged on a right-hand side of the memory cell array and second sense amplifiers are arranged on a left-hand side of the memory cell array. Due to “post-sense coupling” effects upon activation of the sense amplifiers in conjunction with capacitive coupling effects between bit lines, potential changes occur on adjacent bit lines. The integrated semiconductor memory makes it possible to simulate parasitic coupling effects between adjacent bit lines in a functional test in which the first and second sense amplifiers can be activated in temporarily delayed fashion. As a result, the test severity can be improved and test time can be saved.

摘要: A differential amplifier circuit has two input transistors, a load element, and a current source. A terminal for an input voltage is connected to a control terminal of a first input transistor. A terminal for a reference voltage is connected to a control terminal of a second input transistor. The two input transistors are connected in parallel between the load element and a terminal of the current source. A terminal for an internal reference potential is connected to a further terminal of the current source. A regulating circuit, is connected to the terminal for the voltage and to the terminal for the reference potential, and regulates the potential of the circuit dependent on changes in the reference voltage. Fluctuations of the reference voltage are compensated by regulation of the internal reference potential. As a result, the operating point of the circuit is stabilized independently of fluctuations of the reference voltage.
