Abstract

Non-volatile memory block management. A method according to one embodiment includes determining a block health of at least some non-volatile memory blocks of a plurality of non-volatile memory blocks that are configured to store data. An error count margin threshold is calculated for each of the at least some non-volatile memory blocks. A determination is made as to whether the error count margin threshold of any of the at least some non-volatile memory blocks has been exceeded. A memory block management function is triggered upon determining that the error count margin threshold of any of the non-volatile memory blocks has been exceeded.
