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.

Storage device and data processing method thereof

A storage device and a method of operating a storage device including a non-volatile memory. The method includes selecting a first task from among a plurality of tasks queued in a task queue of the storage device; determining whether a mode of the first task is identical to a mode of a previously-executed task; and determining an execution order of the first task according to a result of determination. The modes and the region addresses of tasks may be utilized to group tasks to permit interleaving of programming data.

Storage device and method of operating the same

A method of operating a storage device including a non-volatile memory includes receiving a write command from a host in a first state, receiving write data from the host in a second state, and transitioning an operation state from the second state to one of the first state and a third state based on a write mode chosen. The write command is received in the first state, and the received write data is programmed to the non-volatile memory in the third state.

Storage device

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.

Storage device, system including the same and method of operating the same

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.
