Electronic apparatus, data storage device therefor, and operating method thereof

A data storage device comprising:

• a storage component including a temperature sensor and a plurality of memory dies;
• and
• a memory controller configured to provide a temperature signal based on the temperature sensor to an external device every set period in response to a mode control signal of the external device, and to control the storage component to process a command by simultaneously operating a number of memory dies corresponding to a first performance index as the command including the first performance index is received from the external device,
• wherein the external device is configured to transmit a mode control signal including a start time, an end time and a second performance index to the memory controller, and
• the memory controller is configured to control the storage component to process the command by simultaneously operating a number of memory dies corresponding to the second performance index during a time interval from the start time to the end time.

An operating method of a data storage device, the operating method comprising:

• receiving, by a memory controller configured to control a storage component including a temperature sensor, a mode control signal from an external device;
• transmitting, by the memory controller, a temperature signal based on the temperature sensor to the external device every set period;
• and
• controlling, by the memory controller, the storage component to process a command by simultaneously operating a number of memory dies corresponding to a first performance index as the command including the first performance index is received from the external device,
• wherein the external device is configured to transmit a mode control signal including a start time, an end time and a second performance index to the memory controller, and
• the memory controller is configured to control the storage component to process the command by simultaneously operating a number of memory dies corresponding to the second performance index during a time interval from the start time to the end time.
