Katsuaki Matsui patentsRecent bibliographic sampling of Katsuaki Matsui patents listed/published in the public domain by the USPTO (USPTO Patent Application #,Title):
09/13/12 - 20120230133 - Nonvolatile semiconductor memory device and data writing method
A nonvolatile semiconductor memory quickly and precisely accumulates a desired amount of charges corresponding to data-to-be-written in a charge accumulating part of a memory cell. When charges are injected into the charge accumulating part of the memory cell by applying a writing voltage corresponding to the data-to-be-written to the drain...
Inventors: Katsuaki Matsui, Junya Ogawa (Lapis Semiconductor Co., Ltd.)
12/29/11 - 20110317490 - Nonvolatile semiconductor memory
A nonvolatile semiconductor memory can reduce variations in an amount of current during data writing operation. This allows for the writing of data to memory cells with high precision. The nonvolatile semiconductor memory includes a plurality of memory cells, word lines connected to the memory cells, and bit lines connected...
Inventors: Katsuaki Matsui (Oki Semiconductor Co., Ltd.)
10/01/09 - 20090245002 - Semiconductor memory device having high stability and quality of readout operation
A semiconductor memory cell device includes a first multiplexer selecting a sub-block including a memory cell storing data to be read out in a row, a drain selector selecting a first column line connected to one terminal of the memory cell to be read, a precharge selector selecting a second...
Inventors: Katsuaki Matsui, Junichi Ogane (Oki Semiconductor Co., Ltd.)
07/16/09 - 20090180327 - Non-volatile semiconductor storage device
In a memory cell array which is constituted with flash memory, a pair of a positive memory cell and a negative memory cell, to which data with mutually opposite values are written, is plurally provided. Bit lines and I/O lines connected to the memory cells of a data reading object...

The bibliographic references displayed about Katsuaki Matsui's patents are for a recent sample of Katsuaki Matsui's publicly published patent applications. The inventor/author may have additional bibliographic citations listed at the USPTO.gov. FreshPatents.com is not associated or affiliated in any way with the author/inventor or the United States Patent/Trademark Office but is providing this non-comprehensive sample listing for educational and research purposes using public bibliographic data published and disseminated from the United States Patent/Trademark Office public datafeed. This information is also available for free on the USPTO.gov website. If Katsuaki Matsui filed recent patent applications under another name, spelling or location then those applications could be listed on an alternate page. If no bibliographic references are listed here, it is possible there are no recent filings or there is a technical issue with the listing--in that case, we recommend doing a search on the USPTO.gov website.
