Rice University’s breakthrough silicon oxide technology will allow manufacturers to fabricate “resistive random-access memory” (RRAM) devices at room temperature with conventional production methods, the researchers say. In a new paper in Nano Letters, a Rice team led by chemist James Tour compared its RRAM technology to more than a dozen competing versions.
