Abstract:
Apparatuses and methods for calibrating sense amplifiers in a semiconductor memory are disclosed. An example apparatus includes an amplifier circuit and a calibration circuit. The amplifier circuit is configured to be coupled to a supply voltage and a reference voltage, and when activated the amplifier circuit is configured to provide an output signal at an output that is complementary to an input signal provided to an input. When activated by a calibration signal, the calibration circuit is configured to provide a calibration voltage to the output of the amplifier circuit, wherein the calibration voltage is an equilibration voltage between the supply voltage and the reference voltage provided to the amplifier circuit.
