Abstract:
A method for wear-leveling cells, pages, sub-pages or blocks of a memory such as a flash memory includes receiving (S10) a chunk of data to be written on the cell, page, sub-page or block of the memory; counting (S40), in the received chunk of data, a number of times a given type of binary data ‘0’ or ‘1’ is to be written; and distributing (S50) the writing of the received chunk of data among cells, pages, sub-pages or blocks of the memory such as to wear-level the memory with respect to the number of the given type of binary data ‘0’ or ‘1’ counted in the chunk of data to be written.
