Memory management method for monitoring access to data or programs e.g. for chip card, by allocating attributes to memory addresses to permit or deny access

摘要

The method involves allocating an attribute to each memory unit of the memory (12) to control the access to the memory. The attribute is allocated to a memory address of the memory unit. The attribute is checked for each access to a memory unit by checking the attribute allocated to the memory address of the memory unit and corresponding to the address of the access. Access to the memory unit defined by the address of the access is performed if the attribute permits it. Access is denied if the attribute does not permit it. An Independent claim is included for a chip card.
