    Abstract: A method of controlling discard operations is performed in a system that includes a host device and a data storage device. The method includes providing a shared discard bitmap accessed commonly by the host device and data storage device. The shared discard bitmap includes discard bits in one-to-one correspondence with target sectors of a nonvolatile memory device in the data storage device. The method also includes setting bit values of the discard bits stored in the shared discard bitmap, the bit values indicating whether data stored in each of the target sectors are discardable. An asynchronous discard operation may then be performed with respect to the target sectors based on the bit values of the discard bits stored in the shared discard bitmap.

    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.
