A synchronous signal generator is provided that contains a first and second counting and delay circuit, which both are in a subhierarchical position with respect to a reset signal synchronization/delay circuit. The reset signal synchronization/delay circuit and the first and second counting and delay circuit are triggered by a basic clock signal or a first clock signal derived therefrom to be identical in frequency and phase, and contain counting means whose initial and final counting state are adjustable in order to set, in a clocked fashion, the temporal positions of a first and second load signal that are output by the first counting and delay circuit as well as of a FIFO read clock signal that is output by the second counting and delay circuit and thus adapt them to the temporal requirements of a semiconductor memory system containing the synchronous signal generator.
