Embodiments of the present disclosure relate to a memory system and an operating method thereof. According to the embodiments of the present disclosure, the memory system may monitor, in a state in which an address mapping information corresponding to a target device capable of inputting and outputting data corresponding to a specific address is first address mapping information, a first performance pattern which is an performance pattern for the target device, input information on the first performance pattern to an artificial intelligence engine which analyzes the performance pattern based on an artificial intelligence model and outputs address mapping information for the target device, and remaps a second address mapping information, which is the address mapping information output by the artificial intelligence engine, into address mapping information corresponding to the target device.
