Abstract
To operate a nonvolatile memory system including a nonvolatile memory device and a memory controller, a mapping memory is divided into a plurality of mapping memory regions where the mapping memory stores mapping data representing a mapping relation between a logical address of a host device and a physical address of the nonvolatile memory device. Occupation information representing whether the mapping data are stored in each mapping memory region of the plurality of mapping memory regions are provided. Based on the occupation information, user data are stored in a corresponding mapping memory region of the plurality of mapping memory regions in which the mapping data are not stored.
