Abstract
A memory plane for an archival, non-volatile mass storage memory has a planar semiconductor diode with each of a plurality of small P-N junction diodes alloyed into the surface of its fabricated layer responsive to a selectively-actuated scanned energy beam at each location corresponding to a first binary value in a planar array of data sites. Formation of a P-N junction is prevented at each of the remaining sites of the planar data array to provide storage of data having the remaining binary value. Several alternative methods for formation of the alloy junction surface diodes are disclosed.
