Zusammenfassung: | Wear levelling techniques based on use of a Galois field for the logical to physical translation of data addresses for a non-volatile memory, such as an MRAM-based memory, are presented. This not only provides a wear levelling technique to extend memory life, but also adds an additional layer of security to the stored memory data. More specifically, the following presents embodiments for secure wear levelling based on a Galois field having an order based on the size of the memory. To further improve security, a randomly generated rotation of the logically address based on the Galois field can also be used. |
