摘要： 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.

摘要： An optoelectronic memory cell has a transparent top electrode, a photoactive layer, a latching layer, and a bottom electrode. The photoactive layer absorbs photons transmitted through the top electrode and generates charge carriers. During light exposure, the latching layer changes its resistance under an applied electric field in response to the generation of charge carriers in the photoactive layer.
