Patent abstract

A semiconductor device includes at least two transistors and a charge-trapping structure. The charge-trapping structure traps charges, which are moved from a selected transistor toward a non-selected transistor, adjacent to the selected transistor among the transistors, thereby preventing a threshold voltage of the non-selected transistor from being increased. Thus, the charge-trapping structure traps the charges so that an increase of the threshold voltage of the non-selected voltage is suppressed.
