From: Conductance Quantization in Resistive Random Access Memory
Quantized conductance change behavior under different time intervals [181]. a The conductance change under ten successive voltage pulses of 0.4 V with a pulse width of 20 ms at intervals of 2 s. The conductance state could increase to about 2 G 0 under the input pulses but immediately decays to zero after each input pulse is completed. b The conductance evolution under ten successive voltage pulses of 0.4 V with a width of 20 ms at intervals of 0.2 s. In this case, the conductance gradually increases and maintains at about 1 G 0 for more than 60 s after the tenth input pulse. Reproduced with permission
