Abstract

A method of operating a semiconductor device that includes a variable resistance device, the method including applying a first voltage to the variable resistance device so as to change a resistance value of the variable resistance device from a first resistance value to a second resistance value that is different from the first resistance value; sensing first current flowing through the variable resistance device to which the first voltage is applied; determining whether the first current falls within a predetermined range of current; and if the first current does not fall within the first range of current, applying an additional first voltage that is equal to the first voltage to the variable resistance device.
