Abstract
In a method of operating a semiconductor device, a resistance value of a variable resistance element is changed from a first resistance value to a second resistance value by applying a first voltage to the variable resistance element; and a first current that flows through the variable resistance element is sensed. A second voltage for changing the resistance value of the variable resistance element from the second resistance value to the first resistance value is modulated based on a dispersion of the first current, and the first voltage is re-applied to the variable resistance element based on a dispersion of the first current.
