Memory system and method of operating the same

A method of operating a memory system comprising a memory device, the memory device including a plurality of memory blocks each including a plurality of pages, a plurality of planes each including the plurality of memory blocks, and a plurality of dies each including the plurality of planes, the method comprising:

• managing the plurality of memory blocks as a plurality of super blocks formed by grouping the plurality of memory blocks in a form corresponding to set conditions;
• performing a first operation of classifying and managing, as first super blocks of the plurality of super blocks, super blocks formed by mixing and grouping at least one bad memory block and normal memory blocks;
• performing a second operation of classifying and managing, as second super blocks of the plurality of super blocks, super blocks formed by grouping only normal memory blocks;
• performing a third operation of checking an accumulated size of write data received from a host, and grouping the write data into a plurality of data groups based on a result of the checking of the accumulated size;
• and
• performing a storage operation for storing, each time one data group is formed in the third operation, the formed one data group in N first super blocks among the first super blocks formed in the first operation and M second super blocks among the second super blocks formed in the second operation,
• wherein N is a natural number of 1 or more, and M is the natural number greater than N.
