Abstract: In one example a system includes a memory, and at least one memory controller to: detect a failed first memory location of the memory, remap the failed first location of the memory to a spare second location of the memory based on a pointer stored at the failed first memory location, and wear-level the memory. To wear-level the memory, the memory controller may copy data from the spare second location of the memory to a third location of the memory, and keep the pointer in the failed first memory location.

Abstract: A remapping rate of remapping operations on a memory module may be determined. Each remapping operation may comprise storing a pointer to an unfailed memory location within a failed memory location. A wear-leveling rate on the memory module may be adjusted based on the remapping rate.
