Abstract
The exemplary embodiment comprising a signal reception part and a routing device which routes specific signal information for storage to information memories provided for that purpose. The goal of the disclosure is to create such a signal processing means which, given the lowest possible circuit-technical outlay, always prevents an undesired re-programming of information memories with absolute certainty. This goal is inventively achieved in that a locking register is allocated to a memory bank constructed of a plurality of information memories, in which locking register a locking signal can be inscribed for each information memory which is specifically allocated to this information memory, on the basis of which locking signal a change of the stored informational content is made impossible as long as no opening signal for an appertaining information memory is input into the locking register from the outside.
