Memory system and operating method thereof

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

• starting a booting operation for booting the memory device;
• measuring an initial temperature of the memory device in the booting operation;
• generating, based on whether the initial temperature is within a reference range, monitoring information representing either a booting mode in which the booting operation is continuously performed or a protection mode in which the booting operation is suspended;
• and
• outputting a request whether to continuously perform or suspend the booting operation based on the monitoring information.

A storage device comprising:

• a memory device including a plurality memory cells, each memory cell configured to store data;
• and
• a memory controller in communication with the memory device and configured to control an operation of the memory device,
• wherein the memory device is configured to measure a temperature of the memory device, generate and store monitoring information representing an operation mode that is either a normal mode in which the operation is performed or a protection mode in which the operation is suspended, and provide the memory controller with a signal representing the operation mode of the memory device that is either the normal mode or the protection mode, and wherein the signal is dependent on whether the temperature of the memory device is within a reference range.
