ABSTRACT:
An electronic memory component provides a plurality of access-secured sub-areas. Each access-secured memory sub-area has at least one assigned parameter, for example, an address. The memory encrypts the assigned parameters of the access-secured sub-areas in such a way that on the one hand the security of such devices is increased considerably and on the other hand the associated expense and technical complexity are not too great. The encryption allows access to at least one sub-area dependent on at least one further sub-area.
