1. An apparatus, comprising:

  • a processor configured to;

    determine a storage duration for storage of a data block in a memory, the storage duration configured to indicate a time at which the data block is scheduled to be removed from the memory;

    compute a data block eviction time for the data block based on a probability density function configured to describe a probability of removing the data block from the memory at a time, within a range of time from an initial time to the time at which the data block is scheduled to be removed from the memory, since a last access time of the data block; and

    evict the data block from the memory when the data block eviction time elapses without a subsequent access to the data block.
