    摘要： A circuit for generating a reference voltage for the reading out from and the evaluation of read output signals which are read out with a constant plate voltage from storage cells of a ferroelectric memory via bit lines. In the circuit, a reference voltage device is formed of two reference cells that are subjected to the action of complementary signals. The reference cells can be simultaneously read out in order to generate the reference voltage in a selection and evaluation device.

    摘要： A circuit gives each of the input signals at its inputs to a common circuit previously charged to a supply voltage through transfer transistors. When the logical condition is satisfied the common circuit remains charged; otherwise the charge changes. This is detected by a discriminator circuit and the result is indicated at the circuit output. The circuit may be of AND-, OR-, NAND- and NOR design.

    摘要： An integrated buffer circuit includes a first series circuit connected between a first supply potential and a second supply potential (ground). The first series circuit has a voltage-controlled first constant current source, a first field effect transistor having a gate forming an input of the buffer circuit, a circuit node between the first current source and the first field effect transistor forming an output of the buffer circuit, and a first control input for controlling the first current source with a reference potential having a constant potential difference relative to the first supply potential. A second series circuit is connected between the first supply potential and the second supply potential. The second series circuit has a first resistor, a second constant current source furnishing a current being independent of the first supply potential, and a circuit node between the first resistor and the second current source, establishing the reference potential and being connected to the first control input of the first current source.

    摘要： A semiconductor circuit is disclosed which contains a driving circuit which is integrated into a semiconductor substrate of a first conductivity type and includes positive voltage switching transistors for switching positive and/or zero voltage levels and negative switching transistors for switching negative and/or zero voltage levels. In addition, the driving circuit contains a control circuit which is positioned upstream from the driving circuit and is also embodied in the semiconductor substrate, which is connected to a substrate voltage. A negative voltage switching transistor of the driving circuit is configured inside an outer well which is embedded in the semiconductor substrate and is of a second conductivity type which is opposite to the first, and the outer well is connected to a supply voltage.

    摘要： In a circuit configuration and a method for testing storage cells, all of the bit lines lead to one pair of fault lines which is first precharged with mutually-complementary logic levels. All of the storage cells of a word line are always read-out in parallel relative to one another. In the event of "no fault" the pair of fault lines retains its logic states, whereas in the case of a fault one of the fault lines changes its logic state through switching transistors. This is recognized and analyzed by a comparator circuit in the form of an XOR-circuit or an XNOR-circuit.
