Write current reduction in transition metal oxide based resistance-change memory

초록

A novel memory cell structure with a Pt/Ti-doped NiO/Pt architecture is shown to exhibit the lowest write current reported thus far for a unipolar switching resistance-change-based device, as shown in the figure. The write current decreases dramatically upon scaling to cell sizes smaller than 100 nm x 100 nm. High-density universal memory can be fabricated by combining this node element with a selective switch.
