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.

Dynamic memory management system

A memory system uses a dynamic RAID scheme to dynamically encode RAID address space geometries. The dynamic RAID scheme solves issues with the algorithmic layout approach and flat virtual address space used in conventional RAID systems. The dynamic RAID scheme can be used for any RAID algorithm and does not require static mapping. In other words, there is no requirement that each strip be located in the same relative location in memory devices and there is no requirement that stripes use the same combination of memory devices.
