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.
