To make memristors an international team of researchers (USA – MIT, Lawrence Berkeley National Laboratory, IBM, China, South Korea) first fabricated a negative electrode out of silicon, a positive electrode by depositing a slight amount of copper, followed by a layer of silver. They sandwiched the two electrodes around an amorphous silicon medium patterning a millimeter-square silicon chip with tens of thousands of memristors. When they ran the chip through several visual tasks, the chip was able to “remember” stored images and reproduce them many times over, in versions that were crisper, and cleaner compared with existing memristor designs made with unalloyed elements. Such brain-inspired circuits could be built into small, portable devices, and would carry out complex computational tasks that only today’s supercomputers can handle…read more. TECHNICAL ARTICLE
