A circuit configuration for performing a selective changeover of word lines of a memory matrix between an activation potential and a deactivation potential uses selectively addressable drivers. The changeover of a word line input terminal from the activation potential to the deactivation potential is effected through the relevant driver if a deactivation signal is brought to an active state by a timing control circuit. In order to accelerate the deactivation of the word lines, a respectively assigned deactivation auxiliary switch is connected to each of the word lines at at least one terminal remote from the input terminal. The deactivation auxiliary switch is controlled by a timing control circuit such that it connects the remote terminal to the deactivation potential practically at the same instant at which the assigned driver changes the input terminal of the relevant word line from the activation potential over to the deactivation potential.
