Abstract
A semiconductor device may include a trimming circuit suitable for generating a reference voltage that is adjusted based on a code value, and an internal voltage generation circuit suitable for generating an internal voltage based on the reference voltage, wherein the internal voltage generation circuit is suitable for dividing the internal voltage in a division ratio that varies depending on an operation mode and for generating the internal voltage based on comparison of the divided internal voltage with the reference voltage.
