Abstract
A sensing amplifier of a memory array, a memory device and a data read method with two state reference voltages are provided. The sensing amplifier comprises a sampling circuit, a latch circuit, and a reset circuit. The sampling circuit compares data voltages, a first state reference voltage, and a second state reference voltage according to a bit line pre-charge signal and a word line to generate a first sampling signal on the output node and a second sampling signal on the inverted output node. The latch circuit implements that the first sampling signal and the second sampling signal are inverted signals and latches the first sampling signal on an output node and the second sampling signal on the inverted output node.
