Memeristor is a novel circuit element which is defined using electronic charge q and magnetic flux ~0. In order to study basic properties of memristor based chaos, this paper analyses in detail the basic properties of a chaotic circuit with a cubic smooth characteristic mernristor, including equilibrium set and its stability, transient chaos and its transfer. A method for overcoming the transient chaos and generating stable chaos is proposed, and the FPGA-based digital realization for the memristor based chaotic circuit is investigated, obtaining the expected experimental results.
