ABSTRACT:
In a memory device for storing data according to the FIFO principle, an input counter is provided having a value which is modified when data are written into a memory, and having a comparison unit that outputs a status signal concerning presence of data in the memory dependent on a comparison of the counter states. A scanning unit is arranged at the connection between the comparison unit and the input counter. The scanning unit scans the state of the input counter according to a clock signal and outputs the scan result to the comparison unit.
