Abstract :
In this paper, we fabricated 1T1R NiO-ReRAM test circuits based on 0.18 mum CMOS technology and observed notable suppression of Ireset by imposing current compliance Icomp using a cell transistor. Reducing the stray capacitance between Pt/NiO/Pt and the cell transistor used as a current limiter is crucial in this issue. This enabled the systematic measurement of Icomp dependence of lreset for Icomp < 1 mA and Ireset ap Icomp was observed for 150 muA les Icomp les950 muA.
