Storage device, storage system including the same and operating method thereof

A storage device comprising:

• a non-volatile memory device configured to store a map information data set for converting a logical address into a physical address;
• and
• a storage controller configured to:
• store, based on the map information data set, a mapping table set into a volatile memory;
• receive a first logical address range associated with a first command to be queued in a command queue of a host device;
• and
• store, a first mapping table which is associated with first map information data corresponding to the first logical address range among the map information data set, into the volatile memory.

A method of operating a storage system comprising a host device comprising a command queue configured to queue commands, a non-volatile memory device configured to store a map information data set for converting a logical address into a physical address, and a storage controller configured to store a mapping table set into a volatile memory based on the map information data set, the method comprising:

• transmitting, by the host device, a first logical address range associated with a first command to be queued in the command queue, to the storage controller;
• receiving, by the storage controller, the first logical address range from the host device;
• and
• storing, by the storage controller, a first mapping table associated with first map information data corresponding to the first logical address range among the map information data set, into the volatile memory.
