Abstract
Disclosed are various embodiments related to dual-gate transistors and associated calibration circuitry. In one embodiment, dual-gate transistors may be configured in a sense amplifier arrangement, and calibration circuitry can be used to adjust an input offset of the sense amplifier. In another embodiment, a reference level voltage utilized in an amplifier with dual-gate transistors can be adjusted during a calibration sequence, and may be substantially unchanged from its nominal value outside of the calibration sequence. In another embodiment, a calibration sequence can be utilized to determine circuit results from a circuit including dual-gate transistors, and to adjust control gates to more closely coincide with expected or desired results. In yet another embodiment, a semiconductor memory device can include a memory array with amplifiers that include dual-gate transistors, as well as associated calibration circuitry.
