DEVICE FOR GENERATING INTERNAL POWER SUPPLY VOLTAGE AND METHOD THEREOF

摘要

A device for generating an internal power supply voltage and a method thereof are provided to prevent a starting problem by using the internal power supply voltage as an operation voltage of a reference voltage generation part. A starting voltage generation part(40) generates a starting voltage by using an external power supply voltage. A reference voltage generation part(41) generates a reference voltage by using the starting voltage. An internal power supply voltage generation part(42) generates an internal power supply voltage by using the external power supply voltage in response to the reference voltage. The starting voltage generation part is turned off by the reference voltage generated by the reference voltage generation part.
