Abstract:
A resistive memory device includes a cell block having a plurality of unit memory cells in which a resistive element and a cell select element are connected to each other in series, the cell block operating in response to a word line, a bit line, and a source line, and a dummy line, when different interconnection layers form the source line and the bit line, respectively, connected to one of the interconnection layers which is formed at a lower side the remaining interconnection layer between the interconnection layers for the source line and the bit line, wherein the dummy line has a resistance lower than a resistance of the lower interconnection layer.
Abstract:
An integrated circuit (IC) device may include a single substrate that includes a single chip, and a plurality of memory cells spaced apart from one another on the substrate and having different structures. Manufacturing the IC device may include forming a plurality of first word lines in a first region of the substrate, and forming a plurality of second word lines in or on a second region of the substrate. Capacitors may be formed on the first word lines. Source lines may be formed on the second word lines. An insulation layer that covers the plurality of capacitors and the plurality of source lines may be formed in the first region and the second region. A variable resistance structure may be formed at a location spaced apart from an upper surface of the substrate by a first vertical distance, in the second region.
Abstract:
A scanning device includes a display part, a flat bed on which a manuscript is loaded, a white reference sheet provided at one side of the flat bed, a scanning head to divide the white reference sheet into a plurality of lines and to obtain shading data corresponding to the plurality of lines by scanning the plurality of lines, a storage part in which the shading data for the plurality of lines is stored, and a controller to calculate a maximum value and a minimum value of the shading data by comparing the shading data of each pixel at a same position in the scanning head from the plurality of lines, and to control the display part to display an error message if a difference between the maximum value and the minimum value of the shading data is out of a reference range.
