Memory system storage device with power loss protection circuit

In a method of resetting a storage device, an internal power supply voltage is generated based on an external power supply voltage. A first reset control signal that is activated when a level of the internal power supply voltage is higher than a reference level. A second reset control signal that is activated after a power-on of the storage device is completed or deactivated after a predetermined delay time from when the external power supply voltage is turned off. A final reset control signal is generated based on the first reset control signal and the second reset control signal. The final reset control signal is activated when at least one of the first and second reset control signals is activated. After the external power supply voltage is turned off, a reset operation is performed when the final reset control signal is activated.
