Non-volatile memory data and address encoding for safety coverage

摘要

A method is disclosed for use in an electronic device having a non-volatile storage device and a volatile storage device, the method comprising: retrieving a first encoded data packet from a first address in the non-volatile storage device; decoding the first encoded data packet to obtain a first data item and a first error code corresponding to the first data item, the first encoded data packet being decoded by using a first coding key that is associated with the first address; detecting whether the first data item is corrupt based on the first error code and an error correction function, storing the first data item at a first address in the volatile storage device when the first data item is not corrupt, and transitioning the electronic device into a safe state when the first data item is corrupt.
