Patents by Inventor Kichio Abe

Kichio Abe has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4110840
    Abstract: A random access memory includes a column of static MOS storage cells. Two sense-write conductors are coupled to each cell in the column. Each sense-write conductor is also coupled, respectively, to a termination MOSFET. The first sense-write conductor of each column of storage cells is coupled by means of a first coupling MOSFET to a first bit-sense conductor. The second sense-write conductor of each column of storage cells is coupled, by a second MOSFET to a second bit-sense conductor. Each pair of sense-write conductors is coupled to a V.sub.DD conductor by a separate charging MOSFET having its gate electrode coupled to a circuit for generating a pulse at the end of a write cycle.
    Type: Grant

  • Patent number: 4099265
    Abstract: A random access memory includes a column of static MOS storage cells. Two sense-write write conductors are coupled to each cell in the column. The first sense-write conductor of each column of storage cells is coupled by means of a first coupling MOSFET to a first bit-sense conductor. The second sense-write conductor of each column of storage cells is coupled, by a second MOSFET to a second bit-sense conductor. Each sense-write conductor is coupled to the other by a first MOSFET having its gate electrode coupled to a circuit for generating a pulse in response to an address input transition. A second balancing MOSFET is coupled between the two bit sense conductors and has its gate also coupled to said circuit.
