A tiny device called a memristor holds great promise for a new era of electronics.  Unlike a conventional resistor, its resistance can be reset, and it remembers its resistance.  It functions in a way that is similar to synapses in the human brain, where neurons pass and receive information.  A memristor is a two-terminal device whose resistance depends on the voltages applied to it in the past.  When the voltage is turned off, the resistance remains or remembers where it was previously.  A commercially viable memristor could enable us to move away from flash memory and silicon-based computing to smart energy-efficient computers that operate similarly to the human brain, with the capability to comprehend speech and images, and with highly advanced memory retention.  More information, including DOE research reports, publications, and data collections about memristor technology, is available in the DOE databases and related resources provided below.
