"MATERIALS: Memristors ready for prime time"


Memristors, the fourth passive circuit in electronic circuit theory, have moved a step closer to prototyping with the harnessing of a substrate material that could yield a new memory device by 2009. In April, Hewlett Packard Laboratories researchers claimed to have "discovered" memristors, which joined resistors, capacitors and inductors as the fourth passive circuit postulated by University of California at Berkeley professor Leon Chua in a 1971 paper. Now, HP Labs (Palo Alto, Calif.) said it has demonstrated how to control its memristor material, which changes resistance in response to current flowing through it. The advance promises to speed development of commercial prototype chips for its RRAM (resistive random-access memory) by next year.
