Summary:A method for operating a cache memory having a set having multiple memory blocks configured for storing data blocks. In a write process of a data block into a memory block of the set, the data block is written into the memory block, a relevance rank value of the data block and a first access time rank value are determined. Rank data associated with the memory block are determined using a write rank mapping from the relevance rank value and the first access time rank value, and the determined rank data are stored. If no memory block of the set is free, a memory block that is to be overwritten is selected from the memory blocks of the set based on the rank data, which are associated with the memory blocks, and the data block to be stored is written into the selected memory block by using the write process.
