Abstract
The invention relates to a semiconductor module having a plurality of signal paths for carrying external signals that each contain a setup and hold circuit on the basis of a latch circuit with a full latch and a logic circuit. The latch circuit contains at a beginning of the signal path upstream of the logic circuit a hold latch. The hold latch responds to the leading edge of a fast clock signal derived from the clock signal of the external signal, for the early latching of the external signal and for the decoupling of the hold time from the setup time. The full latch is disposed downstream of the logic circuit for the final latching of the external signal or of a signal derived from the latter.
