1. A method for super block allocation of a plurality of super blocks of a non-volatile memory (“

  • NVM”

    ) for wear leveling, the method comprising;

    selecting a set of super blocks from the plurality of super blocks that satisfy a pre-determined threshold of a total distribution of the number of cycles of the plurality of super blocks;

    allocating a super block of the set of super blocks for wear leveling, wherein the super block is stochastically selected from the set of super blocks; and

    performing wear leveling on the NVM using the allocated super block.
