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.

Abstract: A method, a system and a computer-readable medium for writing to a non-volatile cache memory are provided. The method maintains a write count associated with a set of memory locations. The method then selects a cache replacement policy based on the value of the write count and selecting a block within the set for writing data using the selected cache replacement policy. The selected cache replacement policy can introduce a randomized selection.
