Ionising radiation and electrical stress on nanocrystal memory cell array

arrays. Heavy ion irradiation has no or negligible immediate effects on the nanocrystal MOSFET characteristics, and on the programming window of the cells. By electrically stressing irradiated device, we see accelerated oxide breakdown similar to that previously observed on conventional thin gate oxide MOS capacitors, but no appreciable change of the degradation kinetics in terms of programming window closure and shift. The accelerated breakdown is ascribed to the degradation of the oxide\u2013nitride\u2013oxide (ONO) layer used as control oxide after exposure to ionising irradiation

Ionising Radiation and Electrical Stress on Nanocrystal Memory Cell Array

In this work we focused our attention on the effects of irradiation and electrical stress of NC memory cell arrays. Heavy ion irradiation has no immediate effect. By electrically stressing irradiated device, we see accelerated oxide breakdown, but no appreciable change of the degradation kinetics
