    摘要: A method of operating a resistive switching device includes applying a program stress to a two terminal resistive memory unit. The program stress is applied at a program voltage configured to change a state of the memory unit from a first state to a second state. The method further includes applying a verification/stabilization stress to the two terminal resistive memory unit. The verification/stabilization stress is applied at a verification/stabilization voltage. An erase stress is applied to the two terminal resistive memory unit. The erase stress is applied at an erase voltage configured to change a state of the memory unit from the second state to the first state. The verification/stabilization voltage is between the program voltage and the erase voltage.

    摘要: In accordance with an embodiment of the present invention, a method of operating a resistive switching device includes applying a signal including a pulse on a first access terminal of an access device having the first access terminal and a second access terminal. The second access terminal is coupled to a first terminal of a two terminal resistive switching device. The resistive switching device has 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, a second ramp from the second voltage to a third voltage over a second time period, and a third ramp from the third voltage to a fourth voltage over a third time period. The second ramp and the third ramp have an opposite slope to the first ramp. The sum of the first time period and the second time period is less than the third time period.
