1. A method of configuring a memory device comprising:

  • providing a memory device including a first data storage region including a material that is modifiable by a limited expected lifetime of data from the first data storage region and a second data storage region including a material that is substantially unmodifiable by a limited number of readings of data from the second data storage region;

    storing primary read-support information in the first data storage region that is readable prior to modification of the material by a first data read system;

    storing data of interest in the second data storage region that is ordered, encoded, encrypted, or otherwise structured so that it is readable with use of the primary read-support information;

    providing secondary read-support information on the memory device that is readable by a second data read system, but not the first data read system, for decoding the ordered, encoded, encrypted, or otherwise structured data of interest.
