The invention enables the use of an economical read-only memory together with a rewritable memory. To this end, a memory management logic (2) interacts with a control unit (1), with a read-only memory (3), and with a rewritable memory (4). The data of specified memory areas of the read-only memory (3) are replaced by data stored on the rewritable memory (4). If the control unit (1) accesses the replaced data of the read-only memory (3), the memory management logic (2) redirects this access to the corresponding data stored on the rewritable memory (4). |
