A memory device includes a first electrode, a second electrode, a third electrode, a first variable resistance layer between the first electrode and the third electrode, and a second variable resistance layer between the second electrode and the third electrode. The first, second, and third electrodes, and the first and second variable resistance layers are formed of materials that cause the first variable resistance layer to transition from a high resistance state to a low resistance state when a voltage is applied across the first and second electrodes and maintain the high resistance state when the voltage is cut off, and cause the second variable resistance layer to transition from a high resistance state to a low resistance state when the voltage is applied across the first and second electrodes and transition from the high resistance state to the low resistance state when the voltage is cut off.
