Memristor is a two-terminal nanodevice that has recently attracted the attention of many researchers. Its simple structure, non-volatility behavior, high-density integra-tion, and low-power consumption make the memristor a promising candidate to act as a switch in digital gates for future high-performance and low-power nanocom-puting applications. In this paper, we model the behavior of memristor by using Verilog-A. To investigate its char-acteristics in a circuit, we use the HSPICE simulator. Furthermore, a library of digital gates are provided by using two approaches to make digital gates: the first one is based on material implication (IMP) and the second one is based on crossbar arrays. Finally, we perform a comparison and evaluation between the two methods.
