13. A method comprising:
-
receiving values for programmable flags within a memory device to assign memory blocks to one of two privilege modes;
providing a first address map when the memory device is accessed when an external node on the memory device is set to a first of the two privilege modes; and
providing a second address map when the memory device is accessed when the external node on the memory device is set to a second of the two privilege modes. - View Dependent Claims (14, 15, 16)
