  • Publication number: 20230268924
    Abstract: An electromechanical logic-in-memory device includes a switching unit including a first electrode having a conductive beam and second and third electrodes disposed on both sides of the conductive beam and attracting the conductive beam by electrostatic force, based on an operating voltage applied between the second and third electrodes and the conductive beam, the conductive beam, after being attracted by and adhered to the second or third electrode, maintained to be adhered even when the electrostatic force is removed and a controller determining an operation mode according to types of logic operations included in input data, setting an initial position of the conductive beam by applying the operating voltage to any one of the second and third electrodes, selecting at least one of the first to third electrodes, and applying a predetermined voltage as a true value of a logic value included in the input data.

  • Patent number: 10553578
    Abstract: Provided are an electronic device and control method therefor. The electronic device may include: a first electronic component; a second electronic component electrically connected to the first electronic component via a first line, where the second electronic component receives a data signal from the first electronic component via the first line; and a third electronic component electrically connected to the first electronic component via a second line and electrically connected to the second electronic component. At least a portion of the second line is substantially parallel to at least a portion of the first line. The third electronic component is configured to compare an electrical signal received via the second line to a reference signal and determine whether an electrostatic discharge (ESD) has occurred based on the comparison result, and the second electronic component is configured to control the first electronic component based on the determination result.

  • Patent number: 6841368
    Abstract: Disclosed is the production of difructose dianhydride IV from sugar. A sugar solution is subjected to reaction at room temperature or lower in an acidic buffer of pH 3.0-7.0 in the presence of a levansucrase derived from Z. mobilis to produce levan. The levansucrase is prepared by culturing E. coli BL21 (DE3)/pEL12 (KCTC 8661), harvesting and homogenizing the cells, and isolating levansucrase from the cell homogenate. Levan is purified from the reaction solution and subjected to reaction at 25-50° C. for 3-10 hours in an acidic buffer of pH 3.0-7.0 in the presence of a levan fructotransferase to produce difructose dianhydride IV. The levan fructotransferase is obtained from E. coli JUD81 (KCTC 0877BP). Also, disclosed are a gene coding for the levan fructotransferase and an expression vector pUDAF81 carrying the gene.
