a Modulation of conductance states under identical pulse trains of 5 V showing cycle-to-cycle variations. b LTP and LTD responses to non-identical pulse trains, with device-to-device variations across ten devices. c Retention stability of the device with separate programmed states switched by different electrical pulses. d Cycling endurance of the device measured under program/erase voltages are ±5 V/1 kHz. e The PPF ratio as a function of pulse interval. The inset shows the pulse waveforms used for measurement. f The STDP learning rule implemented with the device using program/erase voltages are ±5 V/1 ms.
