Claim 19:
20. A system comprising:
a boot loader configured to detect a boot state, and to identify a startup state based on the boot state;
a partition register operatively coupled to the boot loader and configured to partition the memory device into at least one secure address region, in accordance with a determination that the startup state satisfies an operating state condition; and
a system processor operatively coupled to the boot loader, configured to obtain, from an external device and in accordance with a determination that the startup state satisfies an operating state condition, one or more addresses of the non-transitory memory device corresponding to at least one secure address region, write to the partition register a partition address associated with the secure address region in accordance with the determination that the startup state satisfies the operating state condition, and further configured to enter an operation state of the processing device in accordance with a determination that the startup state does not satisfy the operating state condition.
