By using the memristor's memory to both store a bit and perform an operationwith a second input bit, simple Boolean logic gates have been built with asingle memristor. The operation makes use of the interaction of current spikes(occasionally called current transients) found in both memristors and otherdevices. The sequential time-based logic methodology allows two logical inputbits to be used on a one-port by sending the bits separated in time. Theresulting logic gate is faster than one relying on memristor's state switching,low power and requires only one memristor. We experimentally demonstrateworking OR and XOR gates made with a single flexible Titanium dioxide sol-gelmemristor.
