A sensing module, a memory device, and a sensing method are provided to perform a read operation so that the un-programmed/programmed state of a memory cell is identified. The sensing module includes a sensing amplifier and a current sink, and both are electrically connected to the memory cell. The sensing amplifier generates a sensing current and identifies the un-programmed/programmed state of the memory cell accordingly. The current sink receives a reference current being equivalent to the summation of the sensing current and a cell current flowing through the memory cell. The reference current is constant, and the sensing current is changed with the cell current. The cell current is generated based on a high read voltage and a low read voltage applied to the memory cell. The sensing current is higher if the memory cell is un-programmed, and the sensing current is lower if the memory cell is programmed.
