ABSTRACT:
Checking an error recognition functionality of a memory circuit including a memory that stores a datum, and a check value circuit that executes the error recognition functionality, is performed by a monitoring circuit. The memory circuit provides the datum to the check value circuit, wherein the check value circuit checks the datum provided thereto for errors and outputs an error signal if an error is present. The monitoring circuit is coupled to the check value circuit and influences the check value circuit, the memory circuit or the datum provided to the check value circuit so that the check value circuit discovers an error in a check in a case of correct execution of the error recognition functionality, and outputs an alarm signal if the check value circuit does not output an error signal upon the influence of the monitoring circuit.
