▎ 摘　　要

NOVELTY - Memristor comprises a lower electrode layer, a functional layer is located on the bottom electrode layer. A barrier layer is positioned on the functional layer, and an upper electrode layer is arranged on the barrier layer. The functional layer has a resistive layer and a resistance layer. USE - Memristor for use in a memristor-based neural morphology calculation chip for realizing electronic synapse and neuron function of an artificial intelligence development. ADVANTAGE - The memristor increases a layer of barrier layer between the functional layer and the upper electrode, thus, by accurately modulating the resistance value of functional layer, the device when the applied erase voltage, when the device voltage is gradually increased, forming unstable filament in the barrier layer, realizing the function of threshold value conversion. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) Memristor-based neural morphology calculation chip. (2) Preparing memristor.
