    • An embodiment of the present invention relates to a multi-bit memory element. According to the embodiment of the present invention, the memory element includes: a substrate; a first electrode placed on the substrate; a first memory part placed on the substrate and the first electrode containing an electrically polarizing material indicating hysteresis; a semiconductor part placed on the first memory part; a source electrode placed on a side of the semiconductor part; a drain electrode placed on the other side of the semiconductor part; a second memory part placed on the semiconductor part, placed between the source electrode and the drain electrode containing the electrically polarizing material indicating hysteresis; and a second electrode placed on the second memory part. When a first operating voltage is applied to the first electrode and a second operating voltage is not applied to the second electrode, a current I_D1 flows in the semiconductor part. When the first operating voltage is not applied to the first electrode and the second operating voltage is applied to the second electrode, a current I_D2 flows in the semiconductor part. When the first operating voltage is applied to the first electrode and the second operating voltage is applied to the second electrode, a current I_D3 (I_D1+I_D2) flows in the semiconductor part and the current I_D1 is larger than the current I_D2.
