A semiconductor device, a semiconductor system, and a control method of a semiconductor device are capable of accurately monitoring the lowest operating voltage of a circuit to be monitored. According to one embodiment, a monitor unit of a semiconductor system includes a voltage monitor that is driven by a second power supply voltage different from a first power supply voltage supplied to an internal circuit that is a circuit to be monitored and monitors the first power supply voltage, and a delay monitor that is driven by the first power supply voltage and monitors the signal propagation period of time of a critical path in the internal circuit.

In order to provide a semiconductor integrated circuit capable of predicting its own lifetime (wear out failure) due to the aged deterioration and notifying a warning, it includes a processor, a temperature sensor, a non-volatile memory, and a comparator formed on the same semiconductor substrate. The comparator compares a temperature measured by the temperature sensor with a predetermined temperature threshold, and the non-volatile memory accumulatively holds the information (cumulative time) about a period having the temperature exceeding the temperature threshold. The semiconductor integrated circuit notifies the outward of a warning when the cumulative time having the temperature exceeding the temperature threshold exceeds a predetermined high temperature time threshold.
