Abstract
In a memory, a zone descriptor contains authorizations to act which may pertain to actions of reading, writing and erasure and which concerns memory words of a zone of the memory controlled by this descriptor. The zone descriptor also has an information element indicating the length of the memory zone by including the address of the next descriptor. An internal zone control signal is produced in order to store a mode of management of the memory zone and, an address corresponding to the end of the zone. The end of zone address is then compared with the addresses delivered by an address counter. A modification of the stored information is prompted when the end of a zone is reached.
