Abstract
In a sense amplifier connected to a bit line pair of a semiconductor memory device, a control gate is connected between an amplifying circuit and a transistor for activating the amplifying circuit. The control gate closes only when either of the bit lines is HIGH. When both the bit line are HIGH or LOW, the amplifying circuit does not operate.
