Extended Data Fig. 7: Effects of read disturbance.
From: Fully hardware-implemented memristor convolutional neural network

To investigate this effect, we set up this experiment by writing all the convolutional kernel weights to two memristor PEs. After programming all the conductance weights smoothly, we physically apply 1,000,000 read pulses (0.2 V) on all weight cells to see how the read operations disturb the weight states. a, Changes in the states of the 936 conductance weightswhile cycling read operations. The grey lines give the changing traces of the states of all cells, and the three coloured lines depict representative evolution trends. b, Conductance evolution of eight memristor states during 106 read cycles. c, Distributions of weight states after 1, 105, 5 × 105 and 106 read cycles.
