Abstract
In an operating method of a memory controller, the memory controller includes a logical-to-logical (L2L) mapping table including mapping information between a first logical area and a second logical area and a logical-to-physical (L2P) mapping table including mapping information between the second logical area and a physical area of a memory device. The operating method includes receiving a first logical address of the first logical area and a first command for changing the L2L mapping table to access first data stored in the memory device through the first logical address, detecting a second logical address of the second logical area mapped to a physical address of the physical area in which the first data is stored, in response to the first command, and changing the L2L mapping table to map the first logical address to the second logical address.
