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.

Abstract: A storage device and an operating method thereof are provided. Provided is a storage device including, a memory cell, and a storage controller which includes a flash controller that performs a data operation on the memory cell, and a processor that executes an RTOS (Real Time Operating System) for controlling the flash controller, wherein the RTOS communicates with the storage controller and operates in a normal operation mode, the RTOS generates a snapshot data in a debug mode when a defect occurs, the RTOS switches to the debug mode through context switching in the normal operation mode, and the RTOS operates in the normal operation mode, when an urgent work occurs, while performing an operation of generating the snapshot data in the debug mode.
