Switching control of resistive switching devices

摘要

Switching current control plays a critical role in the operation of resistive switching devices. Bothnon-state resistance and maximum reset current show strong dependence on the current limit duringnset switching. The dependence in unipolar switching devices can be explained by the power-drivennnature of reset and dynamic competition between set and reset forces. Effective switching controlnimproves device characteristics including uniform resistance distribution and low reset current.nHowever, it also presents challenges for the choice of selection devices and the feasibility ofnunconventional architectures for resistive switching devices. © 2010 American Institute of Physics.nu0004doi:10.1063/1.3532969
