SEMICONDUCTOR DEVICE INCLUDING A VARIABLE RESISTANCE ELEMENT AND METHOD OF OPERATION THE SEMICONDUCTOR DEVICE

摘要

PURPOSE: A semiconductor device including a variable resistor device and an operating method thereof are provided to improve the reliability of the semiconductor device by improving a current distribution of the variable resistor device. CONSTITUTION: A reset voltage is applied to a variable resistor device(S310). A reset current flowing in the variable resistor device is sensed(S320). A set voltage applied to the variable resistor device is controlled based on the distribution of the reset current(S330).The reset voltage is applied to the variable resistor device based on the distribution of the reset current(S330).
