How We Found the Missing Memristor

IEEE Spectrum: How We Found the Missing Memristor:
"Memristor is a contraction of “memory resistor,” because that is exactly its function: to remember its history. A memristor is a two-terminal device whose resistance depends on the magnitude and polarity of the voltage applied to it and the length of time that voltage has been applied."
