发明名称 Selective ECC refresh for on die buffered non-volatile memory
摘要 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.

主权项 1. A method comprising: 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, the second set of non-volatile memory cells configured to store more bits per cell than the first set of non-volatile memory cells; adjusting one or more read voltage thresholds for the first set of non-volatile memory cells in response to determining to perform the ECC refresh; and reading the data from the first set of non-volatile memory cells using the adjusted one or more read voltage thresholds for copying the data to the second set of non-volatile memory cells.
