Abstract: A storage device includes a non-volatile memory device including a plurality of memory blocks; and a memory controller configured to control a garbage collection operation of copying valid data of a source block among the plurality of memory blocks to a destination block. The memory controller is configured to read a logical address stored in a page included in the source block, determine a validity of user data stored in the page included in the source block based on the logical address, read the valid data, which includes the user data determined to be valid, from the non-volatile memory device, and perform a write operation on the destination block by transferring the read valid data to the non-volatile memory device.

Abstract: A method of operating a storage device may include determining a fault condition of the storage device, selecting a fault resilient mode based on the fault condition of the storage device, and operating the storage device in the selected fault resilient mode. The selected fault resilient mode may include one of a power cycle mode, a reformat mode, a reduced capacity read-only mode, a reduced capacity mode, a reduced performance mode, a read-only mode, a partial read-only mode, a temporary read-only mode, a temporary partial read-only mode, or a vulnerable mode. The storage device may be configured to perform a namespace capacity management command received from the host. The namespace capacity management command may include a resize subcommand and/or a zero-size namespace subcommand. The storage device may report the selected fault resilient mode to a host.

Abstract: A storage device includes one or more nonvolatile memories, and a memory controller that controls the nonvolatile memories such that write data of data streams is stored in the nonvolatile memories. The data streams have a first number of requested stream identifiers provided from a host. The memory controller includes a write amount manager that manages information about a data amount of each of the data streams having the requested stream identifiers, a stream manager that maps the first number of the requested stream identifiers with a second number of processing stream identifiers, depending on the information associated with the data amount, such that the data streams are provided to the nonvolatile memories according to the second number of processing stream identifiers, and a mapping manager that manages information about mapping between the first number of the requested stream identifiers and the second number of the processing stream identifiers.
