Resistive Devices and Methods of Operation Thereof

摘要

In one embodiment, a method of operating a resistive switching device includes applying a signal comprising a pulse on a first terminal of a two terminal resistive switching device having the first terminal and a second terminal. The resistive switching device has a first state and a second state. The pulse includes a first ramp from a first voltage to a second voltage over a first time period. The first time period is at least 0.1 times a total time period of the pulse.
