Probability distribution of log(Ron) taken at 0.5 V reading voltage extracted from 50 SET-RESET cycles, each performed for (a) control device “D1” performed over 100 consecutive SET-RESET cycles, (b) device “D2” before, during and 2 weeks after irradiation and (c) device “D3” before, during and immediately after irradiation with γ–rays. Gamma rays are sourced simultaneously from four Cs-137 and two Am-241 point sources.
