Abstract :
Programmable metallization cell (PMC) devices belong to a class of non-volatile ionic resistive memory devices that have already demonstrated tolerance to high total doses of ionizing radiation. In this work, the susceptibility of integrated 1T-1R PMC memory array to ion strike induced single event upsets is analyzed. Circuit simulations that model single event transients in 1T-1R elements are performed using a PMC compact model which captures the voltage driven resistance change mechanism experimentally observed in such devices. The relationship between incident ion LET and change in PMC resistance and its consequent susceptibility to an upset is investigated through both simulation and experiment.
