Approximated SPICE model for memristor

The memristor has drawn the worldwide attention sine HP laboratory released its invention on May 1, 2008 at Nature Letters. Since then many researchers are taking efforts to find its applications in various areas of the information technology. A good model will help to study and seize the behavior characteristics of memristor. In this paper, we proposed a piecewise line approximated memristor model, and tested the approximated model using several test cases. Simulation results show that the proposed approximated model can be well applied.
