1. A method of operating a data storage device comprising:
- powering on or hot plugging a data storage device including a semiconductor memory as a main storage unit;
supplying a first power and a second power to the data storage device;
supplying the first power to internal elements of the data storage device;
charging an auxiliary power supply with the second power after the second power is applied to the data storage device and a predetermined time elapses; and
supplying power from the auxiliary power supply to the internal elements of the data storage device upon a sudden loss of power to the data storage device.

Abstract
A method of operating a data storage device can be provided by receiving first power and second power at a data storage device, that includes a semiconductor memory, upon powering on of the data storage device or hot-plugging of the data storage device. The first power can be applied to the data storage device and the second power can be applied after a delay to an auxiliary power supply included in the data storage device based on when an inrush current, generated from applying the first power, occurred. Related devices are also disclosed.
