Abstract: A semiconductor memory device and a method of operating the semiconductor memory device are provided. The semiconductor memory device includes a memory block including a plurality of sub-blocks, a peripheral circuit configured to perform a program operation on the memory block, and control logic configured to control the peripheral circuit to perform the program operation on the memory block, wherein the program operation comprises programming to program normal data to a first sub-block, allocated to be a normal sub-block, among the plurality of sub-blocks, and programming parity data of the normal data to a second sub-block, allocated to be a backup block, among the plurality of sub-blocks.

Abstract: A display device includes four pixel arrays, a data driver, and a demultiplexer. The data driver is electrically connected to first and second data output lines. The demultiplexer electrically connects first and second data lines to the first data output line and electrically connects third and fourth data lines to the second data output line. The first to fourth pixel arrays are adjacent to the first to fourth data lines, respectively. Each of the first to fourth pixel arrays includes first and second color pixels. The first color pixels in the second pixel array are connected to the second data line, the second color pixels in the second pixel array are connected to the third data line, the second color pixels in the third pixel array are connected to the third data line, and the first color pixels in the third pixel array are connected to the second data line.

Abstract: The present disclosure provides a memory controller including a state detector detecting whether the memory device is in an idle state, a program controller, based on detection information that indicates a state of the memory device, selecting neighboring strings that are adjacent to a string that is coupled to a memory cell, among the memory cells, on which a program operation or a read operation was performed before the detecting, selecting monitoring memory cells that are coupled to at least one word line, the memory cells being a part of the neighboring strings, and controlling the memory device to perform a plurality of loops to program the monitoring memory cells, and a bad block selector selecting a memory block with the monitoring memory cells as a bad block based on a rate of increase in threshold voltage of a threshold voltage distribution of the monitoring memory cells.

Abstract: A laser pressure head module including: a pressure member including: a first light-transmitting member; a second light-transmitting member; and a sealed space between the first light-transmitting member and the second light-transmitting member; and a gas supply unit to supply gas to the sealed space to generate a pressing force. The second light-transmitting member is to be expanded or moved in an external direction by the pressing force.

Abstract: A mold for printing a wiring includes: a bendable part between a first lever part and a second lever part; a first protruding portion protruding from a top face of the bendable part; a second protruding portion protruding from the top face of the bendable part and at one side of the first protruding portion; and a third protruding portion protruding from the top face of the bendable part and at the other side of the first protruding portion. The first and second protruding portions are spaced apart from each other with a first hinge groove therebetween, the first and third protruding portions are spaced apart from each other with a second hinge groove therebetween, and a width of each of the first and second hinge grooves increases as they respectively extends upwardly in the thickness direction.

Abstract: A coating device includes: a stage transfer part including a first long shaft extending in a first direction and a second long shaft extending in a second direction intersecting the first direction; a stage tilting part disposed on the stage transfer part, where the stage tiling part swings about a first swing axis; a stage rotating part disposed on the stage tilting part, where the stage rotating part rotates about a first rotating axis intersecting the first swing axis; a stage aligning part disposed on the stage rotating part, where the stage aligning part includes a first short shaft extending in the first direction and a second short shaft extending in the second direction; and a stage disposed on the stage aligning part, wherein a coating target is seated on the stage, where the stage includes a monitoring camera disposed in a camera seating space defined inside the stage.
