Zusammenfassung:A memory device and a word line driver thereof are provided. The word line driver includes a first word line signal generator, a second word line signal generator, a first voltage generator, and a second voltage generator. The first word line signal generator selects one of a first voltage and a second voltage to generate a first word line signal according a control signal. The second word line signal generator selects one of a third voltage and a fourth voltage to generate a second word line signal according the control signal. The first voltage generator provides the second voltage, and the second voltage generator provides the fourth voltage, where the first voltage generator is independent to the second voltage generator.
