description Circuitry and method for detecting occurrence of a reflow process to an embedded storage device are disclosed. A temperature sensing device includes a resistor, a temperature sensor, and a comparator. The first terminal of the resistor is coupled to a voltage source, and the second terminal of the resistor is coupled to both the first terminal of the temperature sensor and the first input of the comparator. The second terminal of the temperature sensor is grounded and the second input of the comparator is coupled to a reference voltage. The resistance state of the temperature sensor changes from a first resistance state to a second resistance state when the temperature surrounding the temperature sensor reaches a threshold. The comparator generates an output based on the resistance changes of the temperature sensor. The generated output may indicate whether a reflow process has occurred to the embedded storage device.
