Reference voltage generating circuit of semiconductor memory apparatus |
摘要 |
A voltage generating circuit of semiconductor integrated circuit includes: a voltage controller that detects the level of an external supply voltage and outputs a voltage control signal; a voltage supplier that outputs the external supply voltage or a first internal voltage in response to the voltage control signal; and a first reference voltage generator that is supplied with an output voltage of the voltage supplier and generates a first reference voltage.
