Abstract

The memory arrangement includes a first memory arrangement (30) comprising at least one memory area (10) which stores information (20a, 20b, 20c, 20d) which describes position and size of memory areas (25a, 25b, 25c, 25d) in the second memory arrangement (15) used for the execution of a card program. A program routine updates the information in the memory area following a deactivation process which causes a cancellation of the contents of the first memory arrangement, in such way, that corresponding memory areas in the first memory arrangement cover a joined memory area. An Independent claim is provided for a corresponding memory management method.
