In one embodiment, the method includes receiving, at a storage device, a request. The request includes a request message authentication code and write protect information. The write protect information includes at least one of start address information and length information. The start address information indicates a logical block address at which a memory area in a non-volatile memory of the storage device starts, and the length information indicates a length of the memory area. The method also includes generating, at the storage device, a message authentication code based on (1) at least one of the start address information and the length information, and (2) a key stored at the storage device; authenticating, at the storage device, the request based on the generated message authentication code and the request message authentication code; and processing, at the storage device, the request based on a result of the authenticating.

Storage system and method for performing and authenticating write-protection thereof

A storage device is provided. The storage device includes a memory device including a memory cell array configured to store metadata and main data and a storage controller configured to access the memory device and control the memory device, wherein the storage controller is configured to read data from the memory device at a speed adaptively varying to a first read speed or a second read speed according to a state of the memory device, the second read speed being faster than the first read speed.

Storage device and operating method thereof

Various embodiments of the present invention relate to an electronic device and a charging control method therefor. The electronic device may comprise: a connection terminal for performing wired communication with an external electronic device; and at least one processor functionally connected to the connection terminal, wherein the at least one processor detects connection of a charging device through the connection terminal, receives state information of at least one adjacent terminal located next to a power terminal of the connection terminal, and controls charging power to be supplied thereto through the charging device, on the basis of the received state information of the adjacent terminal. In addition, various other embodiments are possible.

Electronic device and charging control method therefor

A storage device includes at least one nonvolatile memory device, a memory controller that controls the at least one nonvolatile memory device, and a fingerprint recognition sensor that recognizes a fingerprint of a user. The at least one nonvolatile memory device includes at least one secure partition area being accessible by a host device when a fingerprint recognized by the fingerprint recognition sensor is the same as an enrolled fingerprint, and a public area being accessible by the host device regardless of a fingerprint recognition operation.

Storage device having fingerprint recognition sensor and operating method thereof

A method of booting a host device includes enabling or disabling a ready boot option within a basic input-output system (BIOS) of a host device. A normal boot is performed to load a first operating system (OS), that is stored in an internal storage of the host device, to a main memory of the host device when the ready boot option is disabled. A boot operation to load a second OS, that is stored in an internal storage of a mobile device, to the main memory of the host device is performed when the ready boot option is enabled. An individualized user environment for the host device, is provided by booting the host device from the mobile device. The individualized user environment is easily realized as the user need only connect the mobile device to a designated USB port of the host device prior to restarting the host device.

System and method for booting a host device from a mobile device

A memory access control method that can prevent a cell hammer phenomenon includes setting at least a part of all the memory cells a safe memory region, and setting the remaining memory cells to a normal memory region. In the safe memory region, some cells set to an enabled state are accessible for data writing or reading, and the remaining cells set to a disabled state are inaccessible. Based on a safe address mapping algorithm, access to all memory cells in the safe memory region is controlled such that access to the enabled memory cells is allowed and access to the disabled memory cells is prevented. The enabled memory cells in the safe memory region are spaced apart from each other by at least one disabled memory cell in a horizontal and/or vertical direction.

Method of controlling memory cell access based on safe address mapping

A memory system includes a memory device including a plurality of blocks and a plurality of page buffers which respectively correspond to the blocks, wherein each of the blocks includes a plurality of pages in which data is stored, and a controller suitable for backing up data, which is stored in a memory included in the controller, in the page buffers when an operation mode is about to change to a power save mode.
