A semiconductor memory device having internal circuits responsive to temperature data, in order to compensate an output characteristic change of the internal circuits and reduce power consumption depending on temperature change, and method thereof are disclosed. The semiconductor memory device may include a temperature sensing circuit and an internal circuit. The temperature sensing circuit may generate and output temperature data in response to ambient temperature of the semiconductor memory device. The internal circuit may adjust an output level of an output signal in response to the temperature data from the temperature sensing circuit.
