Detecting error count deviations for non-volatile memory blocks for advanced non-volatile memory block management

A method, comprising:

• determining, using a controller, a block health of at least some non-volatile memory blocks of a plurality of non-volatile memory blocks;
• wherein the plurality of non-volatile memory blocks are configured to store data;
• calculating an error count margin threshold for each of the at least some non-volatile memory blocks;
• determining whether the error count margin threshold of any of the at least some non-volatile memory blocks has been exceeded;
• and
• triggering a memory block management function upon determining that the error count margin threshold of any of the non-volatile memory blocks has been exceeded.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions readable and/or executable by a controller to cause the controller to:

• determine, by the controller, a block health of at least some non-volatile memory blocks of a plurality of non-volatile memory blocks;
• wherein the plurality of non-volatile memory blocks are configured to store data;
• calculate, by the controller, an error count margin threshold for each of the at least some non-volatile memory blocks;
• determine, by the controller, whether the error count margin threshold of any of the at least some non-volatile memory blocks has been exceeded;
• and
• trigger, by the controller, a memory block management function upon determining that the error count margin threshold of any of the non-volatile memory blocks has been exceeded.
