Abstract
A memristive routing device includes a memristive matrix, mobile dopants moving with the memristive matrix in response to programming electrical fields and remaining stable within the memristive matrix in the absence of the programming electrical fields; and at least three electrodes surrounding the memristive matrix. A method for tuning electrical circuits with a memristive device includes measuring a circuit characteristic and applying a programming voltage to the memristive device which causes motion of dopants within the memristive device to alter the circuit characteristic. A method for increasing a switching speed of a memristive device includes drawing dopants from two geometrically separated locations into close proximity to form two conductive regions and then switching the memristive device to a conductive state by applying a programming voltage which rapidly merges the two conductive regions to form a conductive pathway between a source electrode and a drain electrode.
