Multiresistive Switching Polyoxovanadates

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention discloses a resistive memory cell (ReRAM) that utilizes discrete polyoxovanadate molecules placed as single molecules between two electrodes, typically organized in a one- or two-dimensional fashion. These polyoxovanadates serve as switchable elements that can reliably transition between multiple resistance states at room temperature, enabling multilevel data storage at the level of individual molecules. With minimal energy use, these memory cells can function as highly miniaturized, efficient, and scalable data storage solutions.

Patent Abstract

The invention relates to a resistive memory cell, which is characterized by the following general structure: i) a first electrode; ii) a second electrode; and iii) at least one polyoxovanadate as a discrete molecule (= individual molecule), which is arranged between the first and the second electrode and is adsorbed on the first electrode, wherein the polyoxovanadate is arranged as a discrete molecule (= individual molecule) between the first and second electrodes only one-or two-dimensionally on one plane.
