Abstract
A reference voltage generation circuit generates a reference voltage. An internal voltage generation circuit generates an internal voltage on the basis of the reference voltage generated by the reference voltage generation circuit. A first trimming circuit trims the internal voltage. During trimming of the internal voltage, the first trimming circuit trims an externally supplied first target voltage in accordance with first trimming data. The first trimming circuit ends the trimming when the first target voltage meets a given condition for the reference voltage.
