Abstract: A nonvolatile storage device in accordance with the inventive concepts includes a nonvolatile memory device comprising a first memory area, a second memory area, and a memory controller. The memory controller includes a first register configured to store reliable mode information, and a second register configured to store operating system (OS) image information. The memory controller is configured to receive a command from a host based on the reliable mode information; determine whether the command is a write request for an OS image and whether OS image information accompanying the command matches the OS image information stored in the second register; write the OS image to the first memory area if the OS image information accompanying the command matches the OS image information stored in the second register, and block data migration of the OS image from the first memory area to the second memory area.

Abstract: An open-channel storage device being configured to be controlled by a host including a bad block manager, the open-channel storage device including a buffer memory and a nonvolatile memory device. An operation method of the open-channel storage device includes performing a normal operation under control of the host, detecting a sudden power-off immediately after a program failure associated with a first data block among a plurality of memory blocks included in the nonvolatile memory device while the normal operation is performed, dumping a plurality of user data stored in the buffer memory to a dump block among the plurality of memory blocks in response to the detected sudden power-off, detecting a power-on, and performing a data recovery operation on the plurality of user data stored in the dump block in response to the detected power-on.
