Extended Data Fig. 3: Depression, potentiation, and continuous readout operations of the devices.
From: A memristive deep belief neural network based on silicon synapses

(a) Depression (program) of the device by 200 μs pulses. (b) Potentiation (erase) of the device by 100 μs pulses. (c) The conductance of the device as a function of time after each program pulse by continuously reading the state of the device for 20 seconds. (d) The conductance of the device as a function of time after each erase pulse by continuously reading the state of the device for 20 seconds.
