ABSTRACT:
A circuit configuration having a number of electronic circuit components. The operating state of the circuit components can be set to a reset or erase state by a predetermined control signal applied to the respective circuit component in which state a data content of the circuit component assumes a logic zero value. For the purpose of chronologically successive resetting the data contents of all the circuit components, a selection circuit is provided which is activated to allow the writing of the logic zero value to the circuit components. The selection circuit has a number of opening stages corresponding to the number of circuit components. The opening stages are connected in series one after the other and each circuit component is respectively assigned an opening stage of the selection circuit. Each opening stage with the exception of the first opening stage is activated or driven by an opening signal which is generated by the immediately preceding opening stage, for the purpose of outputting a control signal to the associated circuit component. Following the resetting of the associated circuit component, the opening stage in turn outputs an opening signal for the purpose of driving or activating an immediately succeeding opening stage.
