The memristor is the fourth element in integrated circuitry. Scientists are discovering the mathematic equations used to govern memristors are similiar to those which govern synapses in the brain.

In addition, memristors do not "forget" the voltage charge channeled through them. This will yeild billion-fold times the capacity/performance than current hard drives. That, however, is just one of the multitude of products yet to utilize this incredible new component.
