Abstract
A method for operating a processing unit. The processing unit addresses virtual memory areas in order to access a RAM memory unit and these individual virtual memory areas respectively being mapped onto a physical memory area of the RAM memory unit. A check of the RAM memory unit for errors is performed. If, in the course of this check, a physical memory area of the RAM memory unit is determined to be faulty, this faulty physical memory area is designated as faulty. A check is performed to determine whether a free physical memory area exists in RAM memory unit onto which no virtual memory area is mapped and which is not designated as faulty. If such a free physical memory area exists, the virtual memory area that is currently mapped onto the physical memory area recognized as faulty is henceforth mapped onto this free physical memory area.
