ABSTRACT:
A semiconductor memory device includes a voltage detector configured to detect a voltage level of an external power supply voltage, a first core voltage generation driver configured to operate when the external power supply voltage is in a high level region and a second core voltage generation driver configured to operate when the external power supply voltage is in a low level region.
