Design of a SIMON round function circuit based on memristor

As the fourth fundamental circuit element besides resistance, capacitance and inductance, the memristor is derived using the magnetic flux, charge, voltage, electric current symmetry. It contains the memory function and non-volatile. Based on investigating the operating principle and circuit model of memristor, in this paper a scheme of the SIMON round function circuit is presented utilizing the memristor. In the scheme the structure of memristor and SIMON algorithm are first analyzed, followed by designing the circuit of AND OR NOT logic gate based on the use of memristor. The SIMON round function circuit is designed to achieve the function of break-point memory by taking advantage of the non-volatile characteristic of memristor. Under the condition of TSMC 65nm, the Cadence Virtuoso simulation result shows that the proposed circuit has the correct logic. Compared to the conventional CMOS circuit, the number of components decreases by about 27.8%, and is characterized with low-power consumption.
