Storage device based on flash memory and method for managing super block thereof

A storage device, comprising:

• a memory device including a plurality of memory dies;
• and
• a memory controller configured to match at least one memory block included in each of the plurality of memory dies to each of a plurality of super blocks,
• the memory controller further configured to:
• store meta data in first super blocks among the plurality of super blocks,
• store user data in second super blocks among the plurality of super blocks,
• select first memory blocks from each of the first super blocks,
• release matching of the first memory blocks from each of the first super blocks,
• select second memory blocks from each of the second super blocks,
• release matching of the second memory blocks from each of the second super blocks, and
• generate at least one additional super block based on the first memory blocks and the second memory blocks.

A super block managing method of a storage device including a plurality of memory blocks, the method comprising:

• setting a plurality of super blocks by matching a plurality of memory blocks in numbers of memory blocks;
• selecting at least one memory block from each of the plurality of super blocks;
• and
• generating at least one additional super block based on the selected memory blocks.
