Abstract
Example implementations includes a method of partitioning a non-transitory memory device by detecting a boot state of a processing device including a non-transitory memory device, identifying a startup state of the processing device based on the boot state, and partitioning the memory device into at least one secure address region, in accordance with a determination that the startup state satisfies an operating state condition. Example implementations also include a method of generating a secure partition associated with a non-transitory memory device by identifying a target processing instruction restricted to execution at a secure subsystem of a processing device, assigning to the target processing instruction a secure address, associating the secure address with a secure address region of a non-transitory memory device of the processing device, and generating a secure partition table including the secure address.
