Switching dynamics of memristive device under periodic pulse stimulation

The study of switching dynamics of memristive devices is a topical direction both in fundamental and applied investigation of memristive technologies. The main problem in this field is a stochastic nature of switching between resistive states of memristive device. This feature leads to the large variance of resistive states during switching and difficulties in setting specific intermediate states of memristive device. We propose the novel method of setting intermediate states of memristive device by controlling parameters of external pulse stimulation. We have demonstrated experimentally the possibility of switching and holding the resistive states of memristive device by pulse-width modulation (PWM).
