    Abstract: A non-volatile memory device includes a first chip including a first substrate and a circuit element, and a second chip stacked on the first chip. The second chip includes a second substrate including a first cell region and a second cell region, gate electrodes stacked on the second cell region of the second substrate, wherein the gate electrodes are between the second substrate and the first chip, an upper insulating layer configured to cover the second substrate, dummy pads and input/output pads on the upper insulating layer, a cover layer on the upper insulating layer to cover the dummy pads, wherein the cover layer is configured to expose the input/output pads to an outside, and dummy contact plugs on one side of the second substrate, wherein the dummy contact plugs are configured to penetrate the upper insulating layer and electrically connect the dummy pads and the circuit element.
