A dynamic semiconductor memory has memory cells disposed in a cell field. The memory cells are connected to master word lines by way of a word line driver for driving the memory cells. As a rule, all the master word lines that are located in the segmented cell field are inactive, with at most one master word line being active. The master word lines are switched to an active low state, and a portion of the master word lines in a region of the cell field are inverted by a control device located at the beginning of the cell field. The deactivated master word lines in the cell field are at a ground potential, which, in view of the large number of existing master word lines, advantageously substantially reduces the leakage current that must be applied by the generators.
