Abstract:
1. A method for simulating an integrated circuit magnetoresistive random access memory (MRAM) having a first conductor, a second conductor, and a magnetic tunnel junction (MTJ), the first conductor disposed substantially orthogonal to the second conductor, the MTJ disposed between the first conductor and the second conductor, comprising the steps of: calculating a first current in the first conductor; calculating a second current in the second conductor; calculating a first threshold, the first threshold being a first function of the first current; comparing the second current to the first threshold, if the second current is greater than the first threshold, setting a resistance of the MTJ to a first resistance value; calculating a second threshold, the second threshold being a second function of the first current; comparing the second current to the second threshold, if the second current is less than the second threshold, setting the resistance of the MTJ to a second resistance value; and calculating an MTJ current using the resistance of the MTJ.
