  • Patent number: 10510761
    Abstract: In a region just below an access gate electrode in an SRAM memory cell, a second halo region is formed adjacent to a source-drain region and a first halo region is formed adjacent to a first source-drain region. In a region just below a drive gate electrode, a third halo region is formed adjacent to the third source-drain region and a fourth halo region is formed adjacent to a fourth source-drain region. The second halo region is set to have an impurity concentration higher than the impurity concentration of the first halo region. The third halo region is set to have an impurity concentration higher than the impurity concentration of the fourth halo region. The impurity concentration of the first halo region and the impurity concentration of the fourth halo region are different from each other.

  • Patent number: 8297260
    Abstract: A fuel supply system includes a covering member, a subtank, a first housing on the covering member to project toward the subtank, terminals in the first housing, a second housing fitted to the first housing, and lead wires in the second housing connected respectively to the terminals. The first housing includes a fitting recess opening toward the subtank, and a partition wall dividing the recess into spaces, each of which receives a corresponding terminal. The second housing includes a fitting projection fitted into the recess, a slit dividing the projection into blocks, each of which receives a corresponding terminal, the partition wall being inserted in the slit, and axial holes, each of which accommodates a corresponding wire. Each wire includes a corresponding one of elastic seal members. Each seal member seals a gap between a corresponding wire and a wall surface of a corresponding axial hole.

  • Patent number: 6671201
    Abstract: A method of writing data into a semiconductor memory device including a memory cell to which a power supply potential and a ground potential are provided is disclosed. The method may include generating a negative voltage (GNDL) lower than the ground potential and providing complementary data signals to a bit line pair when writing data to a memory cell wherein the low one of the complementary data signals is essentially the negative voltage. In this way, compensation for a potential increment which may be caused due to a wiring resistance, or the like, of a bit line (BL1) may be provided.
