1. An operating method of a storage device including a non-volatile memory, the operating method comprising:
receiving a first source voltage generated by a power management integrated circuit through a first voltage signal pin;
based on the first source voltage being different from a target voltage of the storage device, controlling the first source voltage to the target voltage while receiving the first source voltage generated by the power management integrated circuit;
receiving a command, which indicates an information request associated with an operation voltage of the storage device, from a host;
transmitting a response, which corresponds to the information request, to the host by using the storage device;
receiving a second source voltage which is generated by the power management integrated circuit and has a voltage level different from the first source voltage, through the first voltage signal pin; and
providing the second source voltage to the non-volatile memory,
wherein the receiving the second source voltage comprises:
generating an internal voltage control signal indicating whether to convert the second source voltage, based on the second source voltage; and
controlling the second source voltage to the target voltage based on the internal voltage control signal.
