Abstract
In an example embodiment, a device comprises a non-volatile memory and wear leveling control circuitry. The non-volatile memory comprises logical memory sectors mapped to physical memory sectors, and a supervisory memory sector configured to store a mapping of the logical memory sectors to memory partitions with user-defined boundaries. The wear leveling control circuitry is configured to: receive and store, in the mapping, wear leveling parameters based on user input, where each memory partition is associated with a wear leveling parameter indicating whether that memory partition is excluded from wear leveling; and determine and apply, to the non-volatile memory, wear leveling characteristics based on the wear leveling parameters, where the wear leveling characteristics identify an amount of wear leveling allowed for each of the memory partitions.
