    subsequent to writing the data in the first memory block, determining that the data written in the first memory block needs to be refreshed; and

    based on determining that the data written in the first memory block needs to be refreshed,(i) if the first memory block has endured at least a threshold number of erase/write cycles, relocating the data from the first memory block to a second memory block of the non-volatile memory, and(ii) if the first memory block has endured less than the threshold number of erase/write cycles, refreshing the data in the first memory block of the non-volatile memory.
