ABSTRACT:
The invention relates to a memory arrangement for processing data and to a method for operating this memory arrangement. The inventive method involves a control signal being transferred together with the data on, with a change in the control signal activating the DLL circuit and synchronizing it to a clock. In this case, the DLL circuit stipulates a sampling time for the data. In line with the invention, after a predetermined length of time within which no data have been read from the memory, the memory is accessed artificially in order to generate a change in the control signal for the DLL circuit.
