An electronic device is provided. The electronic device includes an image sensor for capturing an image; a barrel including a lens group arranged about a first axis perpendicular to the image sensor, a first housing fixed to the barrel; a second housing disposed under the first housing and coupled to the first housing; at least one magnetic substance disposed at one side of the first housing; and at least one coil disposed at one side of the second housing. When power is supplied to the at least one coil, electromagnetic force is generated between the at least one coil and the at least one magnetic substance. And if the electromagnetic force is generated, the first housing rotates clockwise or counterclockwise, and the barrel moves along the first axis.

Portable electronic device and electronic device

A system for managing a queue order may receive queue order registration requests from a plurality of user terminals, generate queue order information of the plurality of user terminals, and broadcast, when the queue order information changes, notification information about the change of the queue order information.

System and method of managing queue order, and terminal device

Example embodiments may relate to a method and an apparatus for reading data stored in a memory, for example, providing a method and an apparatus for controlling a reference voltage based on an error of the stored data. Example embodiments may provide a memory data detecting apparatus including a first voltage comparator to compare a threshold voltage of a memory cell with a first reference voltage, a first data determiner to determine a value of at least one data bit stored in the memory cell according to a result of the comparison, an error verifier to verify whether an error occurs in the determined value, a reference voltage determiner to determine a second reference voltage that is lower than the first reference voltage based on a result of the verification, and a second data determiner to re-determine the value of the data based on the determined second reference voltage.

Memory data detecting apparatus and method for controlling reference voltage based on error in stored data

Provided are memory devices and memory data read methods. A method device may include: a multi-bit cell array; a decision unit that may detect threshold voltages of multi-bit cells of the multi-bit cell array to decide first data from the detected threshold voltages, using a first decision value; an error detector that may detect an error bit of the first data; and a determination unit that may determine whether the decision unit decides second data from the detected threshold voltages using a second decision value, based on a number of detected error bits, the second decision value being different from the first decision value. Through this, it is possible to reduce time spent for reading data stored in the multi-bit cell.

Memory device and memory data read method

A memory device and a method of reading multi-bit data stored in a multi-bit cell array may be provided. The memory device may include a multi-bit cell array including a least one memory page with each memory page having a plurality of multi-bit cells, and a determination unit to divide the plurality of multi-bit cells into a first group and second group. The first group may include multi-bit cells with a threshold voltage higher than a reference voltage. The second group may include multi-bit cells with a threshold voltage lower than the reference voltage. The determination unit may sequentially update the first group and second group while changing the reference voltage.
