  • Publication number: 20220302106
    Abstract: A semiconductor storage device includes a memory cell array and a peripheral circuit disposed at least partially below the memory cell array. The peripheral circuit includes an RC circuit in which a resistive portion and a capacitive portion are electrically connected to each other in series. The resistive portion includes first and second lower conductors at a level that is below the memory cell array, an upper conductor at a level that is above the memory cell array, a first contact that connects the first lower conductor to the upper conductor, and a second contact that connects the upper conductor to the second lower conductor. The first lower conductor, the first contact, the upper conductor, the second contact, and the second lower conductor are electrically connected in series in this order and the first lower conductor is closest to the capacitive portion.

  • Patent number: 7419715
    Abstract: A light diffusing resin film is formed by curing a light-curable liquid resin composition whose indispensable components are a photo-polymerizable monomer (A), an organic compound (B) that is incompatible with the photo-polymerizable monomer (A), a cosolvent (C) that is compatible commonly with the photo-polymerizable monomer (A) and the organic compound (B) that is incompatible with the photo-polymerizable monomer (A), and a photo-polymerization initiator (D), a light diffusing film having the resin film on a film substrate, an edge lighting type backlight unit in which the light diffusing film is used, and a liquid crystal display device provided with the edge lighting type backlight unit.

  • Patent number: 7260012
    Abstract: One end of a fuse is connected to a ground point via a transistor N1A, and the other end thereof is connected to a node VaA. For example, at a fuse connection case, when INTV=“H” is input to the gate of the transistor N1A, the node VaA becomes “L.” At INTV=“L”, a transistor P1A having a low “on” resistance turns ON, and the node VaA is quickly precharged. At INTV=“H”, the transistor N1A turns ON, and the node VaA is quickly discharged.

  • Patent number: 6774714
    Abstract: A functional circuit and a filter are disposed between a first power supply wire capable of being set in a first electric potential of a semiconductor device and a second power supply wire capable of being set in a second electric potential, which is different from the first electric potential. The functional circuit is connected to the first power supply wire or the second power supply wire. Then, the filter transmits a signal inputted or outputted between the outside of the semiconductor device and the functional circuit.
