A storage device generates and stores a key stream and a value stream by extracting from data a plurality of keys and a plurality of values respectively corresponding to the plurality of keys. The storage device includes a controller and a non-volatile memory. The controller receives from a host information about an invalid key included in the key stream together with a compaction command, and performs a compaction operation on the key stream in response to the compaction command. The non-volatile memory stores the key stream and the value stream. The controller merges the key stream with another key stream based on the information about the invalid key in the compaction operation.

Storage device storing data based on key-value and operating method of the same

Provided are a storage device storing data on the basis of key-value and an operating method thereof, wherein the storage device separates and manages a plurality of keys and a plurality of values respectively corresponding to the plurality of keys, and includes a first controller processing a first key and a first value corresponding to the first key, a second controller processing a second key and a second value corresponding to the second key, and a nonvolatile memory storing the first key, the second key, the first value, and the second value, wherein the first key includes information about the second controller regarding a processing core for the second value processed next to the first value.

A personal modular trunk and a modular trunk system employing the personal modular trunk for reducing privacy issues and inconveniences that may arise when a vehicle is shared. The personal modular trunk includes: a trunk body; a first communication unit installed in the trunk body and configured to communicate with a vehicle; a first driving unit installed in the trunk body and configured to transport the trunk body; a first engagement unit installed in the trunk body and configured to engage or disengage with a loading space of the vehicle; and a first control unit configured to control the first communication unit to communicate with the vehicle, control the first driving unit to transport the trunk body toward the vehicle, and control the first engagement unit to engage or disengage with the loading space of the vehicle so that the trunk body is coupled to or separated from the vehicle.

Personal modular trunk and modular trunk system employing the same

A key-value storage device includes a non-volatile memory (NVM) divided into blocks, and a data buffer including a key buffer, a value buffer and a mapping buffer, and a controller including a key-value manager. The key-value manager receives a command and key-pairs including keys and values respectively corresponding to the keys, separates the keys from the values, store the keys in the key buffer and store the values in the value buffer, generates a value stream by combining a set of values stored in the key buffer, generates a key stream by combining a set of keys and merging indices for values respectively corresponding to the keys in the set of keys, and updates a key matrix stored in the mapping buffer and indicating whether an index among the indices of the key stream is related to each one of the blocks of the NVM.

Key-value storage device and operating method

A method of predicting an electronic structure of a material by an electronic apparatus includes receiving user's input data about elements constituting the material; applying the received user's input data to a trained model for estimating a state density of the material; and outputting a first graph representing energy level-by-level state densities of the material output from the trained model, wherein the trained model is trained to generate the first graph based on a plurality of second graphs representing pre-calculated energy level-by-level state densities respectively corresponding to a plurality of pre-input data about elements of various materials and the plurality of pre-input data.

Method and electronic apparatus for predicting electronic structure of material

A portable electronic device according to the present disclosure comprises: a memory for storing moving image data; a touch screen for receiving a touch input related to a summation of the moving image data; and a control unit for generating a summary of the moving image data in response to the touch input, wherein the control unit extracts objects included in the moving image data, detects a section in which at least one object among the extracted objects appears and then disappears, and generates a summary of the moving image data by editing the moving image data on the basis of the detected section.

Mobile terminal and control method thereof

A mobile terminal including a wireless communication processor configured to wireless communicate with a video upload service; a camera; a touchscreen configured to display a preview image received from the camera; and a controller configured to when the image received from the camera starts to be recorded into a video, control the video to be recorded to meet a video upload requirement of the video upload service, and upload the recorded video to the video upload service via the wireless communication processor.

Mobile terminal uploading video in a plurality of formats and controlling method thereof

A mobile terminal including a wireless communication unit configured to perform wireless communication; a camera configured to obtain an image; a display unit configured to display a preview image obtained through the camera; and a controller configured to control the display unit to operate in any one of a first state in which a graphic object relating to an image capturing function is displayed overlapping the preview image and a second state in which the graphic object is not displayed while the preview image is displayed, based on a user request, and when a first pre-set type of touch is sensed in a region on which the preview image is displayed in the second state, control the camera to capture the preview image based on the pre-set type of touch.

Mobile terminal and method of controlling the same

A mobile terminal includes a main body; a front camera disposed at a front side of the main body; a display disposed at the front side of the main body; and a controller configured to control the display such that the display displays a preview image within a first portion of the display, wherein the preview image is obtained via the front camera; displays the preview image within a second portion of the display in response to an input, wherein the first portion includes the second portion and further includes a remaining portion; and displays a second image within the remaining portion of the first portion in response to the input.
