A storage device includes a nonvolatile memory device and a storage controller. The storage controller accesses the nonvolatile memory device based on a request of an external host device. The storage controller sends a signal to the external host device, based a throughput of accessing the nonvolatile memory device being within a specific range.

Storage device, operating method of storage device, and electronic device

A redundant array of independent disks (RAID) storage device including; a memory device including first memory devices configured to store at least one of data chunks and corresponding parity (data chunks/parity) and a second memory device configured to serve as a spare memory region, and a RAID controller including a RAID internal memory configured to store a count table and configured to control performing of a rebuild operation in response to a command received from a host, wherein upon identification of a failed first memory device, the RAID controller accesses used regions of non-failed first memory devices based on the count table and rebuilds data of the failed first memory device using the second memory device.

RAID storage device, host, and RAID system

A storage system includes a processor configured to request a write operation of first data corresponding to a first logical address, and requests a write operation of second data corresponding to a second logical address, a memory module including a nonvolatile memory device configured to store the first data and the second data, and a controller configured to convert the first logical address into a first device logical address, and converts the second logical address into a second device logical address based on the first device logical address and a size of the first data, and a storage device configured to store the first data in the storage device based on the first device logical address, and store the second data in the storage device based on the second device logical address.

Storage system including nonvolatile memory module for converting random logical addresses to sequential logical addresses and operating method of the nonvolatile memory module

A portable communication device having a touch-screen locking unit that can prevent operation of the touch screen due to an unwanted screen touch is disclosed. The device comprises a main body housing having a touch screen. A mount is formed in the main body housing. An input unit is attached to or detached from the mount. A locking unit is provided on the mount and turns on/off a locking state of the touch screen according to attachment/detachment of the input unit. The locking state of the touch screen can be automatically set to an ON/OFF state by attaching/detaching a stylus pen to/from a mounting groove. When the touch screen is carried or kept, a touch screen operation or change according to an external environment can be prevented.

Portable communication device having a touch-screen locking unit

A hinge apparatus for a portable terminal including a first housing, and a second housing rotatably connected to the first housing, includes a first connection terminal mounted on the first housing; a second connection terminal mounted on the second housing; and a connection member straightly reciprocating between the first and second connection terminals while the second housing rotates with an electric connection with the second connection terminal, wherein the connection member makes contact with the first connection terminal when the second housing is folded to the first housing with facing the first housing, and the connection member also moves in a direction of being spaced apart from and withdrawing from the first connection terminal when the second housing rotates in a direction of withdrawing from the first housing.

Hinge apparatus for portable terminal

A camera door opening/shutting apparatus for a portable terminal equipped with a camera lens capable of semi-automatically opening and shutting the camera door of a portable terminal. The apparatus has a door member having a lens hole formed therein, a camera door adapted to open and shut the lens hole, a first door cam providing the rotation axis and a trough, the first door cam extending along the periphery of the camera door and being rotatably connected to the door member, a second door cam having a crest formed thereon, which faces the trough, and being adapted to travel linearly as the first door cam is rotated, a door elastic body; and a door cover having an opening formed therein.
