Abstract: A method, a system and a computer-readable medium for writing to a cache memory are provided. The method comprises maintaining a write count associated with a set, the set containing a memory block associated with a physical block address. A mapping from a logical address to the physical address of the block is also maintained. The method shifts the mapping based on the value of the write count and writes data to the block based on the mapping.
