Abstract
Solid-state storage systems and methods are provided for controlling a wear leveling process for uniform use of the memory cells that replaces worn memory blocks with less frequently used memory blocks. The wear leveling process is performed by changing the physical locations of the storage cells within each memory zone or plane. Reference values of target memory block erase counts and worn memory block erase counts are used for searching target memory blocks to be used as replacements.
