were irradiated with 1.1-GeV Au ions with fluences between 10 10 and 10 12 ions/cm 2 and
evaluated regarding pristine resistance, forming voltage, and data retention. Only for the
highest fluence, the resistance of the pristine state and, in turn, the conducting filament
electroforming, as well as the reset voltage, increased. Even for fluences as high as 10 12
ions/cm 2, only a negligible percentage of the tested devices shows event upsets indicating …
