A nanostructure quick-switch memristor includes an upper electrode, a lower electrode and three layers of nanomembrane provided between the upper electrode and the lower electrode. The three layers of nanomembrane consist of an N-type semiconductor layer, a neutral semiconductor layer on the N-type semiconductor layer, and a P-type semiconductor layer on the neutral semiconductor layer. The nanostructure quick-switch memristor of the present invention has the quick switching speed, simple manufacturing method, and low manufacturing cost.
