A memory interface (1) for controlling access to a program and/or data memory (MEM) is disclosed that is divided into a plurality of memory areas (SROM O..SROM 5.5, EROM O..EROM 7.5, UROM O..UROM 3.5). The memory interface (1) comprises address calculating means (2) for converting a logic memory address (iadr[O-i] into a physical memory address (phys adr[0 j]) by performing a logic operation on the logic memory address (iadr[O-i]) with an offset value (OFFSET BOOT, OFFSET RT1, OFFSET RT2) that is assigned to the given memory area (SROM O..SROM 5.5, EROM O..EROM 7.5, UROM O..UROM 3.5) and that is stored in a volatile offset memory (3). At least one offset value (OFFSET BOOT) is read from a preset address in the program and/or data memory (MEM) therefore.
