Method of outputting temperature data in semiconductor device and temperature data output circuit therefor
A method of outputting temperature data in a semiconductor device and a temperature data output circuit are provided. A pulse signal is generated in response to a booting enable signal activated in response to a power-up signal and the generation is inactivated in response to a mode setting signal during a power-up operation. A comparison signal is generated in response to the pulse signal by comparing a reference voltage independent of temperature with a sense voltage that varies with temperature change. The temperature data is changed in response to the comparison signal. Thus, the temperature data output circuit can rapidly output the exact temperature of the semiconductor device measured during the power-up operation.
