Wear levelling in non-volatile memories

摘要

Broadly speaking, embodiments of the present technique provide an apparatus and methods for improved wear-levelling in non-volatile memory (NVM) devices. In particular, the present wear-levelling techniques operate on small blocks within a memory device, at a finer scale/granularity than that used by common wear-levelling techniques which often remap large blocks (e.g. several kilobytes) of data.
