The embodiment of the invention discloses a digital temperature sensor and a temperature calibration method thereof, and a storage medium. The method comprises: a digital temperature sensor receives atemperature measurement instruction and acquire first temperature information according to the temperature measurement instruction, wherein the first temperature information is to-be-calibrated temperature information; the digital temperature sensor calibrates the first temperature information by using a first parameter to generate second temperature information; the digital temperature sensor acquires a second parameter; and the digital temperature sensor uses the second parameter to calibrate the second temperature information, wherein the third temperature information is the calibrated temperature information. According to the embodiment of the invention, the memory space occupied for parameter calibration of the system is saved; and the calibration precision is improved.
