Abstract
A level of cache memory receives modified data from a higher level of cache memory. A set of cache lines with an index associated with the modified data is identified. The modified data is stored in the set in a cache line with an eviction priority that is at least as high as an eviction priority, before the modified data is stored, of an unmodified cache line with a highest eviction priority among unmodified cache lines in the set.
