According to one embodiment, a circuit system includes an adjusted module, a circuit adjusting module, a power controller, and a set value storage module. The adjusted module operates in a circuit state adjusted by calibration. The circuit adjusting module adjusts the circuit state of the adjusted module by calibration and obtains a set value corresponding to the adjusted circuit state. The power controller stops power supply to at least the adjusted module upon transition to power saving mode and resume the power supply upon return from the power saving mode. The set value storage module non-volatilely stores the set value even in the power saving mode. The circuit adjusting module causes the set value storage module to non-volatilely store the set value upon power-on, and adjusts the circuit state of the adjusted module according to the set value upon return from the power saving mode.
