  • Patent number: 11024364
    Abstract: There are provided a sense amplifier for sensing a multilevel cell and a memory device including the same. The sense amplifier is configured to sense the most significant bit (MSB) and the least significant bit (LSB) of 2-bit data a cell voltage stored in a memory cell as the most significant bit (MSB) and the least significant bit (LSB) of 2-bit data. The sense amplifier senses the MSB of the 2-bit data in a state in which a bit line is electrically disconnected from a holding bit line of the sense amplifier and senses the LSB of the 2-bit data in a state in which the cell bit line is electrically connected to the holding bit line. The sense amplifier is configured to equalize a pair of bit lines of the sense amplifier before sensing the MSB and the LSB of the 2-bit data. The sense amplifier is configured to restore to the memory cell the cell voltage corresponding to the sensed MSB and LSB of the 2-bit data.

  • Patent number: 10232350
    Abstract: A photocatalytic functional film has a structure of a substrate, a barrier layer and a photocatalytic layer stacked one on another. The barrier layer is a SiO2 film, the photocatalyst layer comprises an amorphous TiO2 film, and particles of visible light responsive photocatalytic material formed on the surface of the amorphous TiO2 film. A method for producing a photocatalytic functional film includes: adding an alcohol solvent and an acid to a silicate precursor to obtain a SiO2 sol by dehydration and de-alcoholization reaction; applying and drying the SiO2 sol on a substrate to form a barrier layer; adding an alcohol solvent and an acid to a titanium precursor to obtain a TiO2 amorphous sol by dehydration and de-alcoholization reaction; and applying and drying a composition formed by mixing particles of visible light responsive photocatalyst material with the TiO2 amorphous sol on the barrier layer, to form a photocatalyst layer.
