Controller for managing super block, memory system having the same, and operating method thereof

A memory system comprising:

• a memory device including a plurality of memory blocks in which data is stored;
• and
• a processor configured to:
• identify data stored in the memory blocks as hot data or cold data, according to a comparison result of a hot/cold reference value, and a difference value of a block read count value of an individual memory block with a non-super block and a system read count value of the memory system, and
• control the memory device to copy the hot data or cold data stored in memory blocks included in the non-super block to memory blocks included in a super block, from among the memory blocks,
• wherein the memory blocks included in the super block are capable of operating simultaneously.

A method for operating a memory system, the method comprising:

• updating status information of memory blocks, whenever a read operation of the memory blocks is performed;
• determining data stored in the memory blocks as hot data or cold data, according to a comparison result of a hot/cold reference value, and a difference value of a block read count value of an individual memory block with a non-super block and a system read count value of the memory system included in the status information, when a number of times that the read operation is performed on a memory block reaches a reference number of times among the memory blocks;
• and
• copying, to memory blocks included in a super block, the hot data or cold data stored in a memory block included in the non-super block, from among the memory blocks,
• wherein the memory blocks included in the super block are capable of operating simultaneously.
