Abstract: An operating method of a storage device, may include: adjusting a value of preset electrical energy to be stored in the auxiliary power supply, based on information about first required energy according to process variability of a main system; adjusting a value of electrical energy to be stored in the auxiliary power supply or a value of second required energy, based on information about the second required energy for a temperature of the main system and a required performance of the main system, to obtain an adjusted value of the electrical energy or an adjusted value of the second required energy; and based on the adjusted value of the electrical energy or the adjusted value of the second required energy being greater than a value of available energy of the auxiliary power supply, outputting a signal indicating that the auxiliary power supply operates in a fail mode.
