Abstract
Apparatuses, systems, methods, and computer program products are disclosed for on die buffered non-volatile memory management. A method includes storing data in a first set of non-volatile memory cells. A method includes determining whether to perform an error-correcting code (ECC) refresh for data to be copied from a first set of non-volatile memory cells to a second set of non-volatile memory cells based on one or more attributes associated with the data. A method includes storing data in a second set of non-volatile storage cells representing data using more storage cells per cell than a first set of non-volatile storage cells.
