12. An internal voltage generator of a semiconductor integrated circuit, the internal voltage generator comprising:
-
a level detector that detects a potential level of an external voltage to generate a detection signal; and a first driver that generates an internal voltage by using an internal reference voltage according to an active enable signal activated during an activation mode and the detection signal, wherein when a potential level of the external voltage is higher than a potential level of the internal reference voltage, the detection signal inactivates the first driver. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
