Abstract: A device controller of a storage device including a non-volatile memory peeks a command from a submission queue, and determines whether the peeked command is executable based on a status of device resources. In response to determining that the command is executable, the device controller fetches the command, allocates the device resources to the fetched command, and executes the command.

Abstract: Disclosed is an operation method of a storage device which includes setting a first threshold value for a first host and a second threshold value for a second host under control of a hypervisor, sequentially fetching host commands from the first and second hosts, storing the fetched host commands in an internal command queue, stopping fetching a host command from the first host when the number of first host commands fetched from the first host from among the host commands stored in the internal command queue reaches the first threshold value, and stopping fetching a host command from the second host when the number of second host commands fetched from the second host from among the host commands stored in the internal command queue reaches the second threshold value.

Abstract: A method of operating a storage controller which communicates with a host device and a non-volatile memory device is provided. The method includes: receiving a first command from the host device indicating a read operation of first status information of a first zone random write area (ZRWA) in a first zone region, wherein the first command complies with a zoned namespace (ZNS) standard; obtaining the first status information from a zone status table in the storage controller based on the first command, wherein the first status information indicates at least a portion of a first physical region of the non-volatile memory device corresponding to the first ZRWA in which first data are stored; and providing the first status information to the host device.

Abstract: An operation method of a storage device, which is connected to a host through an interface sharing a memory buffer of the host, includes receiving an access command from the host, anticipating data that is expected to be requested by the host with reference to the access command, reading out the anticipated data from a nonvolatile memory device and loading the read data to a first area of the memory buffer, and in a case of being requested to load the anticipated data into a second area of the memory buffer by the host, moving the anticipated data from the first area to the second area.

Abstract: A storage system may include a host device, and a storage device. The storage device may be configured to, being powered-on, perform an eye open monitor (EOM) operation with respect to a signal received from the host device to generate an EOM result value, configured to store the EOM result value in a buffer memory, and configured to output the EOM result value in the buffer memory to the host device in response to receiving an asynchronous event request (AER) command from the host device.

Abstract: A controller is included in a storage device communicating with a host device. The controller is configured to receive a firmware image download command and a firmware image corresponding to the firmware image download command from the host device, perform verification for determining whether the firmware image is damaged in response to the received firmware image download command, and when a firmware update request for the firmware image is received from the host device, determine whether to perform a firmware update based on the firmware image by using a verification result of the firmware image.
