High-speed simulator including accurate MTJ models for spintronics integrated circuit design

An extremely practical simulation program with integrated circuits emphasis (SPICE) incorporating model parameters of magnetic tunnel junction (MTJ) was developed. The simulator provides reliable simulation results in spintronics circuit design because it can accurately calculate various MTJ characteristics that actual devices have, that considerably influence the operation margin and power dissipation. It can also accelerate the simulation speed, which makes it possible to simulate three times or more large-scale circuits than when a conventional macro-model is used.
