  • Patent number: 7486544
    Abstract: The present invention provides a semiconductor integrated circuit device having an SRAM in which leak current is reduced. In an SRAM comprising a plurality of memory cells each constructed by a storage in which input and output terminals of two inverter circuits are cross-connected and a selection MOSFET provided between the storage and complementary bit lines and whose gate is connected to a word line, a substrate bias switching circuit is provided. In normal operation, the substrate bias switching circuit supplies a power source voltage to an N-type well in which a P-channel MOSFET of a memory cell is formed and supplies a ground potential of the circuit to a P-type well in which an N-channel MOSFET is formed.

  • Publication number: 20080311340
    Abstract: A honeycomb structure excellent in thermal dispersibility upon heating and being protected from damage due to thermal stress, and an efficient method for manufacturing the honeycomb structure. The structure is provided with porous partition walls, functioning as a filtration layer, through which exhaust gas flowing into the cells can flow out, and plugging portions. Additional plugging portions are further disposed in the open end portions to which the plugging portions are not disposed (unplugged open end portions) not so as to plug unplugged open end portions. Each cross-sectional shape of additional plugging portions in a direction perpendicular to the axial direction forms a predetermined pattern shape as a whole, and a barycenter of the pattern shape is located in almost the center of a cross section of a flow of the exhaust gas in a direction perpendicular to the axial direction.

  • Publication number: 20080258177
    Abstract: Wirings connected to a gate electrode of a slave switch circuit cell for substrate bias circuits are respectively electrically connected to a wiring for a power supply potential and a wiring for a reference potential. Thus, the switch operation of the slave switch circuit cell is made invalid. Wirings connected to n wells of respective circuit cells are electrically connected to a wiring for the power supply potential, and wirings connected to p wells of the respective circuit cells are electrically connected to the wiring. Thus, the n wells are fixed to the power supply potential, and the p wells are fixed to the reference potential.

  • Patent number: 7317658
    Abstract: A semiconductor integrated circuit has a memory which can enter active state or standby state, and the memory has voltage generation circuits for bit lines and source lines with which memory cells are connected. The voltage generation circuits make the potential of the bit lines and the potential of the source lines equal to each other in response to an instruction to transition from active state to standby state. The voltage generation circuits produce a potential difference between the bit lines and the source lines in response to an instruction to transition from standby state to active state. In standby state, the potential of the bit lines and that of the source lines are equal to each other. Therefore, sub-threshold leakage does not occur between the source and drain of each memory cell. In active state, the source line potential is not varied.
