Abstract
The memory device includes an auxiliary memory and a useful memory. Both memories are provided with a plurality of memory entries. The auxiliary memory is intended for storing regions of an address space therein. This includes a plurality of addresses with which the useful memory may be addressed. A write/read access to a useful memory entry is not possible if a status field associated with the useful memory entry signals a restricting status and the address with which the useful memory entry is addressed lies within at least one of the address space regions stored in the auxiliary memory. Efficient region-selective flushing of the useful memory is possible with this procedure.
