An anti-ghosting keyboard includes a sensing unit, a detection unit, and a processing unit. The sensing unit includes a plurality of sensing modules, each of which includes N number of switches and N number of sensing resistors, where N is a positive integer greater than one. The detection unit includes a divider resistor that is connected in series with one of the sensing modules, and a detection module that is connected to a point of connection between the sensing unit and the divider resistor. The detection module obtains a divided voltage value across the divider resistor and generates a potential level value based on the divided voltage value. The processing unit is electrically connected to the detection module for receiving the potential level value therefrom, and generates a key-press signal that corresponds to the one of the sensing modules based on the potential level value thus received.
