The special any-polar resistive switching mode includes the coexistence and stable conversion between the unipolar and the bipolar resistive switching mode under the same compliance *** the present work,the any-polar resistive switching mode is demonstrated when thin Ti intercalations are introduced into both sides of Pt/HfO_(2)/Pt RRAM *** role of the Ti intercalations contributes to the fulfillment of the any-polar resistive switching working mechanism,which lies in the filament constructed by the oxygen vacancies and the effective storage of the oxygen ion at both sides of the electrode interface.
