Memristors are a class of recently discovered electronic circuit components that are passive, and as fundamental as resistors, capacitors, and inductors. A memristor behaves as a variable resistor whose resistance varies with the amount and direction of current flow across it. When no voltage is applied, the memristor maintains the last state it was in, storing information without the need to be powered. This behavior is similar to long-term potentiation (LTP) in synapses. Like synapses, memristors can increase their conductivity with stimulation over time. I will design and fabricate memristors in a cleanroom for later use as synapses in artificial neural networks. Device testing will be done using a field-programmable gate array at William and Mary.
