Claim 4:
5. The semiconductor memory device of claim 4, wherein the first switch circuit includes a first circuit block, a second circuit block, a third circuit block, and a fourth circuit block,
wherein the first circuit block switches a plurality of voltages and transmits a switched voltage to the second circuit block,
wherein the second circuit block selectively outputs the voltage that is received from the first circuit block to any one of a first output terminal and a second output terminal,
wherein the third circuit block selectively outputs any one of an internal low voltage, an external power voltage, a core voltage, and a ground voltage to the first output terminal, and
wherein the fourth circuit block selects any one of the internal low voltage, the external power voltage, the core voltage, and the ground voltage and outputs the selected one to the second output terminal.
