Abstract

A method of operating a memory device that includes groups of memory cells is presented. The groups include a first group of memory cells. Each one of the groups has a respective physical address and is initially associated with a respective logical address. The device also includes an additional group of memory cells that has a physical address but is not initially associated with a logical address. In the method, a difference in the future endurance between the first group of memory cells and the additional group of memory cells is identified. When the difference in the future endurance between the first group and the additional group exceeds a predetermined threshold difference, the association between the first group and the logical address initially associated with the first group is ended and the additional group is associated with the logical address that was initially associated with the first group.
