    Abstract: A display device according to an embodiment includes a first power module that receives AC power from an external power supply, a second power module that receives the AC power through the first power module, and a load circuit that outputs a specified signal when a user input is received. A configuration of the display device with the three power modules reduces an inrush current when the display device is turned on. Also, a configuration of the display device with the three power modules reduces a standby power consumption when the display device is not turned on.

    Abstract: An image sensor includes a separation impurity layer in a semiconductor layer and defining a photoelectric conversion region and a readout circuit region, a photoelectric conversion layer in the semiconductor layer of the photoelectric conversion region and surrounded by the separation impurity layer, a floating diffusion region spaced apart from the photoelectric conversion layer and in the semiconductor layer of the photoelectric conversion region, a transfer gate electrode between the photoelectric conversion layer and the floating diffusion region, and impurity regions in the semiconductor layer of the readout circuit region. When the photoelectric conversion layer is integrated with photo-charges, the separation impurity layer has a first potential level around the photoelectric conversion layer and a second potential level on a portion between the photoelectric conversion layer and the impurity regions of the readout circuit region. The second potential level is greater than the first potential level.

    Abstract: According to an embodiment, an electronic device may include a display, a memory, and at least one processor operatively coupled to the display and the memory. The memory stores instructions that are configured to, when executed, enable the at least one processor to display first stroke data of a first stroke trajectory, based on an input of a first touch-move after a first touch-down on the display, perform shape recognition on the first stroke trajectory, based on a size of the first stroke trajectory and a distance between a stroke start point of the first stroke trajectory and another point on the first stroke trajectory, convert the first stroke data into second stroke data corresponding to a recognized shape form, based on the shape recognition, and display the second stroke data on the display. Various other embodiments may be possible.

    CPC classification number: G06F12/1027

    Abstract: A memory management unit includes a TLB configured to cache PTEs including a mapping between a virtual and a physical frame number, and to convert a virtual address into a physical address using the cached PTEs. A page table walk request queue is configured to queue page requests corresponding to a virtual page number when a TLB miss is occurred, and one or more PTWs are configured to acquire a PTE from the main memory, and to convert the virtual page numbers into physical frame numbers using the PTE. A PTW is configured to select associated page table walk requests having the same base address of corresponding virtual page numbers, to consecutively provide cache line requests for acquiring PTEs corresponding to the associated page table walk requests, to acquire the PTEs corresponding to the associated PTE requests, and to provide the acquired PTEs to the TLB.
