A method implemented by a memory controller may comprise receiving segment pointers that identify memory devices and slices for associated segments. The method may comprise identifying a most-full first one of the memory devices. The method may comprise identifying a most-empty second one of the memory devices. The method may comprise identifying one of the segments in the most-full one of the memory devices. The method may comprise moving a slice from the identified one of the segments in the most-full one of the memory devices to the most-empty one of the memory devices. The method may comprise updating one of the segment pointers for the identified segment.
