Storage device providing hardware initialization retry function and method of operating the same

A method of operating a storage device, the method comprising:

• monitoring a plurality of first monitoring signals generated by a plurality of power circuits;
• generating a retry request in response to detection of hardware initialization failure in at least one power circuit of the plurality of power circuits based on the plurality of first monitoring signals;
• receiving a plurality of second monitoring signals generated by the plurality of power circuits and a control circuit;
• and
• performing a hardware initialization operation for the at least one power circuit based on the retry request and the plurality of second monitoring signals.

A storage device comprising:

• a nonvolatile memory;
• a plurality of power circuits configured to operate sequentially to drive the storage device;
• and
• processing circuitry connected to the nonvolatile memory and the plurality of power circuits, the processing circuitry configured to, in response to detecting failure of a hardware initialization operation of at least one power circuit of the plurality of power circuits,
• suspend entry into an error mode of the storage device, and
• retry a hardware initialization operation for the at least one power circuit.
