Abstract
A temperature detecting circuit is provided. The temperature detecting circuit includes a reference and detection voltage generator for generating a reference voltage corresponding to a first and a second reference current, and changing first to M-th (M being a natural number) detection currents based on first to M-th temperature detection codes to generate first to M-th detection voltages corresponding to the changed first to M-th detection currents and the second reference current; a temperature detection signal generator for comparing each of the first to M-th detection voltages with the reference voltage to generate first to M-th temperature detection signals; and a temperature detection controller for detecting an operation temperature of a semiconductor device while changing the first to M-th temperature detection codes in response to the first to M-th temperature detection signals from the temperature detection signal generator.
