A crossbar array of Cu/TaOx/Pt cells. The cell A marked by the red dot represents the heat source cell. The cells affected by the heat source are disposed along the Cu and Pt line and marked by black crosses and Xi and Yj. All these probed cells are set prior to heating by cell A to an ON-state under various Icc constraints. Immediately after the heating of cell A has ended, the conductivity of the cells Xi and Yj is probed at small voltage bias ≤ 0.1 V.
