Abstract:
A drive circuit for controlling an operating mode change of a voltage generator in a memory component, the drive circuit comprises:a control signal input for receiving one of an activation signal and a deactivation signal for the voltage generator; a control signal output outputting a control output signal to the voltage generator; a delay element having an input and an output and generating a delay duration; and a control logic circuit connected to said control signal input, said control signal output and said delay element, said control logic circuit: in an event of a signal change from the activation signal to the deactivation signal at said control signal input, switches through the deactivation signal to said control signal output directly if the delay duration prescribed by said delay element has been exceeded; and in an event of a signal change from the activation signal to the deactivation signal at said control signal input, switches through the deactivation signal to said control signal output in a manner delayed by the delay duration prescribed by said delay element, if the delay duration has been undershot.
