A method for operating a semiconductor memory device having first and second bit lines, a gate electrode, an insulative layer, and a substrate includes applying first, second, and third biases to the first bit line, the second bit line, and the gate electrode, respectively, to induce carriers from the gate electrode to the insulative layer, where the carriers have the same type of conductivity as majority carriers in the substrate to thereby reduce a threshold voltage of the semiconductor memory device.
