Abstract: In a method of operating a memory system including a memory device and a memory controller, the memory controller reads fail information from a fail info region included in the memory device. The memory controller maps a logical address related to a program to a physical address of a safe region based on the fail information to store the program in the safe region except the fail info region and a fail region included in the memory device. The memory controller loads the program into the safe region of the memory device according to the address mapping. The method of operating the memory system according to example embodiments increases the performance of the memory system.
