Abstract:
Example apparatus, systems and methods receive a new firmware image at a memory device and place the new firmware image into second nonvolatile storage locations of the memory device such that the second nonvolatile storage locations do not overlap with first nonvolatile storage locations of the memory device that store a current firmware image. Embodiments place a logical address to physical address mapping for the new firmware image into a remap data structure stored in memory circuits of the memory device. The remap data structure also includes a logical address to physical address mapping for the current firmware image. Embodiments provide a first status value to indicate that the logical address to physical address mapping for the new firmware image is a valid firmware image and a second status value to indicate that the logical address to physical address mapping for the current firmware image is an invalid firmware image.
