Abstract
Methods of wear leveling in a memory, and memories configured to perform such methods, are useful in extending cycling endurance in memories. Such methods include transferring data from a first block of the memory to a second block of the memory, erasing the first block, transferring data from a third block of the memory to the first block, erasing the third block, transferring data from the second block to the third block, swapping logical addresses for the first block and the third block with each other, and erasing the second block. Transferring data from the third block to the first block excludes a sub-sector of the third block that is to be erased.
