Claim 15:
16. The stacked memory device according to claim 14, further comprising:
a third voltage generator coupled to the first word line signal generators to provide the first voltage; and
a fourth voltage generator coupled to the second word line signal generators to provide the third voltage,
wherein each of the first voltage generator and the second voltage generator is a first voltage level shifter, the first voltage generator determines a voltage value of the second voltage according to a logic level of a first selection signal, and the second voltage generator determines a voltage value of the fourth voltage according to a logic level of a second selection signal; each of the third voltage generator and the fourth voltage generator is a second voltage level shifter, the third voltage generator determines a voltage value of the first voltage according to a logic level of a third selection signal, and the fourth voltage generator a voltage value of the third voltage according to a logic level of a fourth selection signal.
