An apparatus for checking an error recognition functionality of a memory circuit, wherein the memory circuit includes a memory circuit that stores a datum and a check value circuit that executes the error recognition functionality and a monitoring circuit, wherein 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, wherein 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 would discover 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.
