Abstract: A memory (SP) is provided with sectors (S1,...,Sm) where at least one row (Z1,...,Zn) forms each sector and a number of keys (K1,...,Kk) are provided. For each application a number of sectors are provided of variable seize. At least one access right (AC) and at least one connection (SI) is assigned to each row (Z1,...,Zn). At least one key is allocated to each row and the rows can be provided either with or without the keys. All rows with the same connections form a virtual sector.
