    Resistive switching in Ni/SiO 2 /Si programmable metallization cells was investigated. The proposed switching mechanism is the formation and dissolution of Ni filaments. Under positive bias, Ni cations migrate through SiO 2 and are reduced at the cathode forming filaments. The filaments are dissolved by Joule-heating effect under positive or negative voltages. Promising resistive-switching characteristics, such as a large resistance ratio of ∼400, excellent data retention, and good immunity to read disturbance, are also revealed.
