Abstract
A semiconductor device includes a reference current generator suitable for generating a reference current, a current-voltage converter suitable for generating a first reference voltage and a second reference voltage in response to the reference current, and an analog-digital converter suitable for generating a digital code value based on a voltage difference between the first and second reference voltages, wherein the reference current generator includes a current control unit for controlling the reference current in response to the digital code value.
