Abstract
A method of wear leveling for a non-volatile memory is disclosed. A non-volatile memory is divided into windows and gaps, with each gap between two adjacent windows. The windows comprise physical blocks mapped to logical addresses, and the gaps comprise physical blocks not mapped to logical addresses. The windows are shifted through the non-volatile memory in which the mapping to the physical blocks in the window to be shifted is changed to the physical blocks in the gap.
