ABSTRACT:
Binary information is stored in a semiconductor archival memory medium by formation of a region of an alloy, of the semiconductor material and a non-doping material, at each of a plurality of potential memory sites at which a first binary value of information is to be stored, with the remaining data sites being devoid of the alloyed region to store the remaining value of binary data. Methods for writing the formation of the alloyed region, and reading the information value stored at each memory site, are also disclosed.
