Abstract
Methods of operating semiconductor devices that include variable resistance devices, the methods including writing first data to a semiconductor device by applying a reset pulse voltage to the variable resistance device so that the variable resistance device is switched from a first resistance state to a second resistance state, and writing second data to the semiconductor device by applying a set pulse voltage to the variable resistance device so that the variable resistance device is switched from the second resistance state to the first resistance state to the second resistance state. The reset pulse voltage is higher than the set pulse voltage, and a resistance in the second resistance state is greater than in the first resistance state.
