Abstract
A method allows the use of inexpensive read-only memory together with rewriteable memory. To this end, a memory management logic unit interacts with a control unit, with a read-only memory and with a rewriteable memory. The data, in particular memory areas of the read-only memory, have been replaced with data in the rewriteable memory. If the control unit accesses the replaced data in the read-only memory, the memory management logic unit diverts this access to the corresponding data in the rewriteable memory.
