  • Publication number: 20230195386
    Abstract: In a method of writing data in a storage device, a data write request is received from a host device. Spatial information is received from a spatial sensor included in the storage device based on the data write request. A logical storage area management table is updated based on the data write request and the spatial information such that target data to be stored is written into a target storage area corresponding to the spatial information among a plurality of logical storage areas. A program command and the target data are transmitted to a nonvolatile memory such that the target data is programmed into a physical storage area in the nonvolatile memory corresponding to the target storage area.

  • Publication number: 20230153038
    Abstract: A storage device configured to be connected to a redundant array of inexpensive disk (RAID) controller includes a plurality of non-volatile memories. A memory controller is configured to control the plurality of non-volatile memories to store data distributed by the RAID controller based on a RAID configuration signal received from the RAID controller. The memory controller is configured to perform self-diagnosis on the plurality of non-volatile memories to determine whether at least one of the plurality of non-volatile memories has an uncorrectable error when a RAID configuration signal is deactivated.

  • Publication number: 20230152984
    Abstract: A storage device includes a nonvolatile memory device (NVM) and a storage controller. The NVM includes a first region configured to store user data and a second region not allocated to a user. The storage controller is configured to be connected with a host device through both a first-type bus and a second-type bus different from the first-type bus. The storage controller is configured to receive a first and second request from the host device through the first-type bus. In response to the first request, the storage controller is configured to perform an operation on the NVM. In response to the second request, the storage controller is configured to store first data associated with the storage device in the second region and access the second-type bus to obtain second data of at least one external device obtained by the host device and store the second data in the second region.
