Abstract
A circuit has a control signal input, a control signal output, a delay element for generating a delay duration, and a control logic circuit. The latter controls the delay element and switches a change in the state at the control signal input to the control signal output in a manner delayed by the delay element, if a minimum time interval between state changes at the control signal input is undershot. The circuit is employed in DRAMs for controlling the active times of the voltage generators present in DRAMs.
