  • Semiconductor memory device and operating method thereof
    Patent number: 10062452
    Abstract: A semiconductor memory device may include a memory core unit including a plurality of memory cells suitable for storing data, an error correction code (ECC) control unit suitable for detecting an error of the data to output a flag signal corresponding to a result of detection of the error, and an address control unit suitable for adjusting a refresh interval of at least one memory cell that stores data in which the error is detected, or repairing the memory cell among the memory cells, in response to the flag signal.
    Type: Grant

  • Method for preparing microporous polyolefin film by thermally-induced phase separation method
    Patent number: 9505899
    Abstract: The present invention discloses a method for preparing a microporous polyolefin film comprising: a step of injecting a composition comprising polyolefin 30 to 60 wt % and a diluent, which can make liquid-liquid phase separation with the polyolefin thermodynamically 40 to 70 wt %, into an extruding machine, and melting and kneading thereof to prepare a single phase melt; and a step of extruding the melt while conducting liquid-liquid phase separation by passing through a section having the temperature below the liquid-liquid phase separation temperature and forming thereof in the form of a sheet, and a microporous polyolefin film prepared according to the method.
