Abstract
A method for storing data in an archival memory semiconductor target by inducing damage to the semiconductor lattice at selected ones of a plurality of storage sites arranged as a two-dimensional array upon a surface of the target. Ions are accelerated and collimated as a beam to impinge upon a target surface to induce the damage to a controlled depth, whereby subsequent illumination of a damaged data site by an electron beam will allow the beam-produced electron-hole pairs to recombine within the damaged area to prevent increased current flow and read a binary zero bit, while hole migrations through a target depletion region will cause increased current flow, at an undamaged data site, to indicate a binary one data bit.
