Abstract: A memory controller controls a nonvolatile memory device including a plurality of user blocks and a plurality of reserved blocks. A ratio of the number of used reserved blocks among the reserved blocks during a predetermined period to an operation count during the predetermined period is calculated and an end of lifetime warning signal to an external device based on the calculated ratio is transmitted. Bad blocks among the user blocks are replaced by one or more of the reserved blocks If at least one block among the user blocks becomes a bad block, the memory controller replaces the bad block with any one of the reserved blocks, and the reserved block used indicates a reserved block replaced with at least one of the user blocks. The operation count can be, for example, an erase count of the nonvolatile memory device, a program count of the nonvolatile memory device, and/or a time count indicating usage time.

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.

Abstract: An operation method of a storage device includes receiving quality of service (QoS) information of a plurality of virtual channels and storing the QoS information. A nonvolatile memory is accessed using different schemes according to the stored QoS information and commands received by virtual channels. The virtual channels are channels through which the storage device communicates with an external device.
