ABSTRACT:
Electronic memory update methods, systems, and related data structures are disclosed. When a memory update is to be performed, a first section of the memory is updated to store a first software code segment, under control of a second software code segment stored in a second section of the memory. The second section of the memory is then updated under control of the first software code segment, after completion of updating the first software code segment. An incomplete update of one of the first and second sections of memory may be subsequently detected and remedied by executing the software code segment stored in the other of the first and second sections of the memory. The risk and effects of incomplete memory updates are thereby substantially reduced.
