Storage device and operating method thereof

A memory controller comprising:

• a host interface configured to receive an analog connection request signal provided by a host;
• and
• a host access controller configured to control access by the host according to host information acquired from the connection request signal,
• wherein the connection request signal includes a set waveform repeated a certain number of times with a distance between adjacent waveforms,
• wherein the host information includes at least one of information on amplitude of the waveform, on total length of the waveform, and on the distance between adjacent waveforms, and
• wherein the waveform is included in the connection request signal.

A method for operating a storage device including a memory device including a plurality of memory blocks and a memory controller configured to control the memory device, the method comprising:

• loading system information stored in the memory device in a booting operation of the storage device;
• receiving an analog connection request signal provided by a host and an Out of Band (OOB) signal;
• providing, to the host, a signal in response to the OOB signal;
• and
• controlling access by the host according to host information acquired from the connection request signal.
