Tunable resistance switching characteristics in a thin FeOx- transition layer part II: Sweeping voltage controlling

Multilevel resistance switching characteristics of the thin FeO
_x
-transition layer were studies by controlling the maximum stopped voltage during reset process. It is obtained that the HRS is mainly influenced by the stopped voltage value, which is nearly independent to the LRS. Moreover, statistics of set and reset electrical parameters show that the possible switching process is localized, and also, the multiple resistive switching states in the TiN/SiO
₂
/FeO
_x
/Fe memristor could be approved.
