Microdensity in space using microelectronic circuits

Single event phenomena in biological organisms are compared with similar phenomena in microeletronic circuits and the similarities and differences are discussed. Both types of phenomena appear to obey the same model, at least to first order. The general applicability of this first-order model appears to reflect the need to operate despite the noise inherent in the storage and processing of information within microscopic volume elements. Arrays of p-n junctions, each having dimensions of a few microns, are proposed as solid state microdosimeters.
