Low power, high reliability magnetic flip-flop

Abstract

A new design of a non-volatile magnetic flip-flop is presented. The use of a magnetic tunnel junction (MTJ) to store the information brings non-volatility to logic circuits and promises zero standby power. It is based on the thermally assisted switching (TAS) approach and the pre-charge sense amplifier. By using STMicroelectronics' CMOS 0.13um design kit and a precise TAS-MTJ compact model, transient functional simulations and Monte Carlo statistical analysis have been carried out to show, respectively, its low power and high reliability performances.
