Abstract:
1. A method of wear leveling cells in a non-volatile memory device, the method comprising: copying a data pattern of a swap partition of the memory device into a spare partition of the memory device, the swap partition being a logical partition mapped to a physical partition addressable by a host external to the memory device, the swap partition data pattern including data in a first physical partition and a second physical partition, the copying of the data pattern excluding data in a physical parameter partition, the spare partition being a logical partition mapped to a physical partition outside of the host address space; reassigning the logical address of the swap partition to the physical spare partition to rotate the physical location of the swap partition data pattern; and repeating the copying and reassigning every time a triggering event occurs to iteratively swap partitions of the memory device.
