Disclosed is an operation method including generating RAID parity data based on first data in response to an RAID enable request and a first write request, the RAID enable request and the first write request being received from an external host, the RAID enable request including a first stream identifier and a RAID enable indication, and the first write request including the first stream identifier and the first data, storing the first data and the RAID parity data based on the first stream identifier, storing second data based on a second stream identifier in response to receiving a second write request from the external host, the second write request including the second stream identifier and the second data, and receiving an RAID disable request from the external host, the RAID disable request including the first stream identifier and a RAID disable indication.

Operation methods of storage devices, and operation methods of storage systems including hosts and storage devices

A storage device including a memory controller and an operating method of the memory controller are provided. The storage device includes a non-volatile memory device including a write buffer configured to store write data provided from a host and a journal buffer configured to store a journal log, a volatile memory device configured to temporarily store metadata, and a memory controller configured to provide the non-volatile memory device with a journaling command, that includes the journal log and the physical address corresponding to the journal buffer, and which issues a command to store the journal log in the journal buffer, to update the metadata temporarily stored in the volatile memory device, and to control the volatile memory device to store updated metadata to the non-volatile memory device.

Storage device including memory controller implementing journaling and operating method of the memory controller

A storage device which is connected to a host using a virtual memory includes a solid state drive that receives a streaming access command including a logical block address (LBA) list and a chunk size, and prefetches stream data requested according to the LBA list and the chunk size from a nonvolatile memory device without an additional command. The prefetched stream data is sequentially loaded onto a buffer, and an in-storage computing block accesses a streaming region registered on the virtual memory to sequentially read the stream data loaded onto the buffer in units of the chunk size. The buffer is mapped onto a virtual memory address of the streaming region.

Storage device processing stream data, system including the same, and operation method

Disclosed are a storage device including a memory controller and a method of operating the memory controller. A storage device according to the technical idea of the present disclosure includes a write buffer for storing write data that is not grouped into a transaction, a non-volatile memory device including a journal buffer where journal logs are stored, a volatile memory device for temporarily storing first metadata, and a memory controller for updating the first metadata to the second metadata based on the journal log stored after the start of the checkpoint among the journal logs stored in the journal buffer.

Storage device including memory controller and operating method of memory controller

Storage device processing stream data, system including the same, and operation method thereof

A method of operating a computing device includes a storage device receiving a request to execute an application instance, and executing the application instance at the storage device in response to the received request by the storage device. The application instance includes a plurality of storage instances connected with one another, and at least one of the plurality of storage instances is connected to a host device.

Operating methods of computing devices comprising storage devices including nonvolatile memory devices, buffer memories and controllers

A method of searching for data in a storage device is provided. The method includes determining, by the storage device, selectivity about read units of the storage device based on a query, with respect to each table stored in the storage device and searching for the data in the storage device based on the selectivity about the read units.

Method for searching for data in storage device

The present invention relates to a display device. According to the present invention, the display device comprises: a display body from which an image is outputted; and a flip hinge assembly which is coupled with the display body, wherein the flip hinge assembly comprises: a fixing unit that is fixed to the display body; a rotation unit that is coupled with the fixing unit to allow rotation thereon; a first elastic member that is coupled with the rotation unit and the fixing unit; and a second elastic member that has one end coupled with the fixing unit, and has the other end selectively contacted with the rotation unit, wherein said second elastic member provides, to the rotation unit, an elastic force which is opposite to an elastic force provided to the rotation unit by the first elastic member. Thus, according to the present invention, an initial tilting angle of the display body is automatically set, thereby increasing user convenience.
