Abstract

Es wird eine programmgesteuerte Einheit mit einem Speicher zum Speichern von Daten, und mit einer Speicherschutzvorrichtung zum Schützen des Speichers vor Lese- und/oder Schreibzugriffen durch hierzu nicht autorisierte Personen beschrieben. Die beschriebene programmgesteuerte Einheit zeichnet sich dadurch aus, daß die Speicherschutzvorrichtung eine Schutzverletzung signalisiert, wenn eine hierzu nicht autorisierte Person versucht, bei aktiviertem Leseschutz einen Lesezugriff auf den Speicher durchzuführen, und/oder wenn eine hierzu nicht autorisierte Person versucht, bei aktiviertem Schreibschutz einen Schreibzugriff auf den Speicher durchzuführen, und/oder wenn eine hierzu nicht autorisierte Person versucht, durch einen entsprechenden Zugriff auf die Speicherschutzvorrichtung den Leseschutz und/oder den Schreibschutz zu deaktivieren oder umzukonfigurieren.
