Memristor Working Condition Analysis Based on SPICE Model
Memristors are novel devices behaving like nonlinear resistors with memory. The concept was first proposed and described by Leon Chua in 1971. In 2008, HP lab proved its existence by announcing its first physical implementation as crossbar structures. A memristor has shown many advantages such as non-volatility and no leakage current. The logic value can be measured in terms of impedance and storing logic values without power consumption, which may cause significant effect on digital circuits. A detailed working condition of a nonlinear dopant drift model of a memristor is studied and a set of precise working condition has been found. The transition time between off and on states of a memristor is proposed as a kind of measurement of the switching behavior.
