Characteristics of 1S1R frame.
(a) Typical I-V characteristics of a CoOx/IGZO/CoOx selector and (b) endurance test under 104 consecutive DC sweeps. (c) Typical I-V characteristics of Pt/CoOx/IGZO/CoOx/Pt (1S) integrated with Pt/TaOx/TiN (1R) after completion of electrical connection. (d) Endurance test measured by a 100-ns pulse width signal. (e) Dependence of normalized read margin (ΔVout/Vpu) on the crossbar line number (N) for 1R (red color) and 1S1R (Black color) devices. The insets of (c,d) show I-V curve and endurance characteristics of only 1R.’
