Abstract

A non-volatile memory device comprises an application code sector of sufficient size to store a first copy of an application code and a second copy of the application code; and a boot sector having a boot loader code embodied therein. The boot loader code is configured to cause a processor to check the integrity of both the first and second copies of the application code; if the first copy is corrupted, overwrite the first copy of the application code with the second copy; and if the second copy is corrupted, overwrite the second copy of the application code with the first copy.
