Abstract

In order to operate an integrated dynamic memory having a memory cell array having bit lines and word lines a plurality of individual actions—to be performed for a memory access—from the activation of one of the word lines up to the precharging of the word lines are controlled in a synchronized manner with a clock signal. A value for defining a defined number of clock cycles between at least two individual actions is programmed at the beginning. For this purpose, a control circuit has a programmable unit. In this way, in conjunction with a clocked circuit, a comparatively high data throughput is made possible even at variable clock frequencies.
