    摘要: A method and semiconductor circuit with which a self-test can be generated and tested with commands by which memory banks are interrogated simultaneously includes a processor for carrying out a built-in self-test and generating commands, each for testing only a respective single memory bank, and an additional processor connected downstream forms more complex multibank commands. Such multibank command formation enables a more diverse test of memories and is carried out faster. Principally, such multibank command generation using a combination of conventional single-bank commands has the advantage of not redeveloping a conventional BIST processor from scratch. It is necessary merely to connect a logic circuit downstream, with which conventional commands are combined, to form the multibank commands. As a result, complex self-test commands that simultaneously access a plurality of memory banks can be generated by a very low development outlay.

    摘要: A pulse generator circuit, in particular for use in or for integrated circuits, which, in the usual way, has a number of inverting elements connected in series, a logic combining element and a delay element. A buffer circuit provided in accordance with the invention ensures that a minimum pulse length of the output pulse generated in response to the input signal is ensured even in the case of an input signal of a very short duration.

    摘要: An integrated circuit has a differential amplifier in a basic circuit having two input transistors, a load element and a power source. The power source has an N-type channel MOS transistor whose controlled path is connected to the input transistors and to a supply terminal of the power source. A control terminal of the transistor is connected to a potential that is positive with respect to a reference potential. The supply terminal of the power source is connected to a potential which is negative with respect to the reference potential and which is made available by a voltage source for switching off cell field transistors of a DRAM memory. The gate-source voltage that is increased in this way improves the behavior of the circuit with respect to fluctuations in potential and permits more favorable dimensioning of the transistor.

    摘要: A dynamic semiconductor memory device of the random access type having an initialization circuit which controls the switch-on operation of the semiconductor memory device and of its circuit components. The initialization circuit supplies a supply voltage stable signal once the supply voltage has been stabilized after the switching-on of the semiconductor memory device. The initialization circuit has an advance detector circuit, which detects a predetermined level state of an externally applied clock control signal chronologically before the supply voltage stable signal is generated and, as a reaction to this, supplies a first enable signal for unlatching the control circuit provided for the proper operation of the semiconductor memory device.
