Abstract: A storage device includes a memory device including a metadata area and a journal data area. A memory controller is configured to control the memory device to write a metadata block to the metadata area and to write a journal data block to the journal data area. The metadata block includes metadata, and the journal data block includes both journal data and metadata storage information. The journal data includes log information pertaining to the metadata, and the metadata storage information includes information pertaining to storage of the metadata block.

Abstract: An operating method performed by a storage device includes selecting a first task from among a plurality of tasks queuing in a command queue of the storage device, checking a first block to be accessed by the first task using a mapping table loaded to the storage device, determining whether the first block is a read reclaim target or a replacement target, and determining an order of executing the first task depending on whether the first block is the read reclaim target or the replacement target.

Abstract: A method of operating a storage device includes receiving a write task from a host device. The method also includes storing the write task in a task queue included in the storage device. A write execution command is received from the host device. The method includes executing the write task in response to the write execution command and performing an internal management operation of the storage device after the write task is stored in the task queue and before the write execution command is received. The response time of the storage device to the write execution command is reduced and performance of the system is enhanced by performing the internal management operation such as the data backup operation during the queuing stage and the ready stage in advance before receiving the write execution command.

Abstract: A method of processing data in a storage device includes writing first data to a data storage unit of the storage device upon receiving the first data from an external host of the storage device, outputting a message to the external host indicating completion of writing the first data to the data storage unit, and determining whether a first data unit included in the first data is redundant in the data storage unit. Determining whether the first data unit is redundant is performed subsequent to or in parallel with writing the first data to the data storage unit.
