  • Publication number: 20190265910
    Abstract: A memory system connectable to a host includes a nonvolatile memory that includes a plurality of blocks, and a controller that is electrically connected to the nonvolatile memory. The controller is configured to determine whether or not write data received from the host has system data characteristics based on tag information received from the host along with the write data, and to write first write data designated as data having the system data characteristics according to the received tag information into a first block for writing first type data having a first level update frequency, and write second write data not designated as data having the system data characteristics according to the received tag information into a second block for writing second type data having a second level update frequency lower than the first level update frequency.

  • Patent number: 7646460
    Abstract: A liquid crystal panel and a liquid crystal display device having stable liquid crystal alignment, excellent display quality, and high display response speed are obtained. In this liquid crystal panel, uneven portions for bending the alignment of liquid crystal molecules towards the direction along the substrate surface are installed on the surfaces where the liquid crystal layer contacts its adjacent layers, and the liquid crystal layer comprises a liquid crystal having a positive dielectric constant anisotropy, and a polymer obtained by subjecting a polymerizable compound in the liquid crystal layer to irradiation with active energy rays, with or without application of a voltage.

  • Patent number: 7605874
    Abstract: A polyimide film is formed in only the peripheries of picture elements defined by gate bus lines and data bus lines. The areas where the polyimide film is formed have higher thresholds of transmittance-voltage (T-V) characteristics than the areas without polyimide films. Discolor can be suppressed by providing a plurality of areas having different T-V characteristics within each picture element as described above.
