Memory system and method of operating thereof, and computer-readable storage medium

A method of operating a memory system, comprising:

• performing, by a memory controller coupled to a non-volatile memory, a wear leveling process by swapping a first storage group having a first group write count with a second storage group having a second group write count, the non-volatile memory including a storage area,
• wherein the first storage group is included in a plurality of first storage groups located in a first area of the non-volatile memory and the second group is included in a plurality of second storage groups in a second area of the non-volatile memory,
• wherein the first area supports physical addressing, and the second area does not support physical addressing,
• wherein the first group write count is a maximum group write count among a plurality of group write counts corresponding to the plurality of first storage groups, and
• wherein the second group write count is a minimum group write count among a plurality of group write counts corresponding to the plurality of second storage groups.

A non-transitory computer-readable storage medium storing instructions, which when executed by a processor, cause the processor to:

• perform a wear leveling process by swapping a first storage group having a first group write count with a second storage group having a second group write count, the first storage group and the second storage group being associated with a non-volatile memory,
• wherein the first storage group is included in a plurality of first storage groups located in a first area of the non-volatile memory and the second group is included in a plurality of storage groups in a second area of the non-volatile memory,
• wherein the first area supports physical addressing, and the second area does not support physical addressing,
• wherein the first group write count is a maximum group write count among a plurality of group write counts corresponding to the plurality of first storage groups, and
• wherein the second group write count is a minimum group write count among a plurality of group write counts corresponding to the plurality of second storage groups.
