摘要:
An integrated semiconductor circuit can have memory cells, which can be read by word lines and bit lines. Two mutually adjacent bit lines in each case are connected to inputs of the same signal amplifier. In order to compensate for parasitic capacitors, which arise at thin sidewall insulations between the patterned word lines and adjacent bit line contacts, additional contact structures which lead past the word lines and represent dummy contacts can be provided. The additional parasitic capacitances produced by the dummy contact alter the electrical potential of the respective reference bit line at the signal amplifier like the parasitic capacitances of activated bit lines, as a result of which the measured differential potential can be corrected with respect to the parasitic effects.

An integrated semiconductor circuit includes a cell array having memory cells which can be read by word lines and bit lines. Two bit lines in each case are connected to inputs of the same signal amplifier. In order to compensate for parasitic capacitances which arise at thin sidewall insulations between the patterned word lines and adjacent bit line contacts which connect the bit lines located at a higher level to the active regions located at a deeper level, two additional word lines and dummy contacts of the bit lines are dummy contacts lead past this additional word lines. The additional parasitic capacitances produced by the dummy contacts alter the electrical potential of the respective reference bit line at the signal amplifier in the same way as the parasitic capacitances of activated bit lines, as a result of which the measured differential potential is corrected with respect to the parasitic effects.

A voltage generator arrangement supplies a largely constant output voltage with a high current driver capability. A bandgap reference circuit is downstream from an impedance converter and downstream a voltage generator. The bandgap reference circuit and the impedance converter on the one hand and the voltage generator on the other hand are connected to different reference ground potential line. The impedance converter contains a charge pump circuit to provide increased control potential, which drives the voltage generator. The voltage generator in contrast produces a reduced output potential. The influence of any voltage drop on that reference ground potential line to which the voltage generator is connected in the output potential is thus likewise reduced.

A circuit configuration for the bit-parallel outputting the bits of a data word includes at least two signal lines for feeding the data signals representing the bits of the data word to driver stages and to a reference circuit. Further driver stages are connected in parallel with the driver stages and have inputs connected to the control device. The control device establishes the signal states of the data signals to be transferred on each signal line and generates a control signal depending on the type and number of the signal state changes of bit sequences to be transferred. It is possible to drive the driver stages that assigned to the signal line for which a signal state change is present.

A voltage generator arrangement supplies a largely constant output voltage with a high current driver capability. A bandgap reference circuit drives a voltage generator on the output side, if necessary via an impedance converter. The bandgap reference circuit and the impedance converter on the one hand, and the voltage generator on the other hand, are connected to different reference ground potential lines. The voltage generator on the output side is preceded by a correction circuit, which corrects for the voltage drop on that reference ground potential line to which the output-side voltage generator is connected. The voltage generator arrangement is suitable for a greater integration density.

A circuit configuration has a first driver stage for feeding in an input signal and for outputting an amplified signal. A second driver stage, which is connected in parallel with the first driver stage, is fed, on the input side, both the input signal and a control signal from a reference circuit connected upstream. The reference circuit compares the feedback level of an output signal, which level is present at one of its inputs, with the level of the input signal present at its other input and generates the control signal for driving the driver stage in the event that the level of the output signal is lower than the level of the input signal. As a result, the driver stage is connected for additional amplification of the input signal.

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.
