Electronic device and method for controlling temperature thereof

摘要

A method for controlling a temperature of an electronic device which includes a semiconductor chip is provided. The temperature control method includes measuring a temperature of a measurement point using the electronic device, comparing the temperature of the measurement point with a target temperature varying according to a period of time when the semiconductor chip operates using the electronic device, and decreasing a clock frequency of the semiconductor chip using the electronic device when the temperature of the measurement point is higher than the target temperature.
