    Abstract: Provided are a memory device for implementing a multi-level memory and a method of implementing a multi-level memory by using the memory device. The memory device includes first and second electrodes apart from each other, a self-selecting memory layer between the first and second electrodes having an ovonic threshold switching characteristic, including a chalcogenide-based material, and configured to have a threshold voltage varying depending on a polarity of and strength of a voltage applied thereto, and a resistive memory layer between the second electrode and the self-selecting memory layer and having a resistance characteristic varying depending on a voltage applied thereto. The memory device is configured to implement multi-level resistance states by changing at least one of a pulse polarity, a number of pulses, pulse height, and a pulse width of a voltage applied between the first and second electrodes.
