Toshiba Corporation is a Japanese multinational conglomerate corporation headquartered in Tokyo, Japan. Its diversified products and services include information technology and communications equipment and systems, electronic components and materials, power systems, industrial and social infrastructure systems, consumer electronics, household appliances, medical equipment, office equipment, lighting and logistics.Toshiba was founded in 1938 as Tokyo Shibaura Electric K.K. through the merger of Shibaura Seisaku-sho and Tokyo Denki . The company name was officially changed to Toshiba Corporation in 1978. Toshiba has made numerous corporate acquisitions during its history, including of Semp in 1977, of Westinghouse Electric Company in 2006, of Landis+Gyr in 2011, and of IBM's point-of-sale business in 2012.Toshiba is organised into four business groupings: the Digital Products Group, the Electronic Devices Group, the Home Appliances Group and the Social Infrastructure Group. In 2010, Toshiba was the world's fifth-largest personal computer vendor measured by revenues . In the same year, it was also the world's fourth-largest manufacturer of semiconductors by revenues .Toshiba is listed on the Tokyo Stock Exchange, where it is a constituent of the Nikkei 225 and TOPIX indices, the Osaka Securities Exchange, the Nagoya Stock Exchange and the London Stock Exchange.

Toshiba Corporation | Date: 2016-01-12

A wireless communication apparatus supports at least a second wireless communication scheme between a first wireless communication scheme and the second wireless communication scheme. The first wireless communication scheme requires that a wireless medium is determined to be busy when a reception level is equal to or greater than a minimum reception sensitivity level of a physical scheme. The apparatus includes a first processing unit and a second processing unit. The first processing unit is configured to set a value lower than a maximum transmission power of the first wireless communication scheme, for a maximum transmission power of the second wireless communication scheme and set a value greater than the minimum reception sensitivity level of the physical scheme, for a carrier sense level, when the second wireless communication scheme is used. The second processing unit is configured to carry out carrier sense using the carrier sense level.

A storage device of an embodiment includes a voltage measurement unit that measures a voltage of power supplied from a host, a volatile memory, a non-volatile memory including a saving area and a normal area, a data compression and decompression unit, and a controller. The controller includes a power-supply voltage determining unit which compares the voltage measured by the voltage measurement unit to a predetermined threshold value, a data saving unit which writes compression user data obtained by compressing user data by the data compression and decompression unit in the saving area when the voltage is less than the predetermined threshold value and the user data is included in the volatile memory, and a data rewriting unit which writes the compression user data that is decompressed in the normal area when the compression user data is included in the saving area at the time of supplying the power.

A three dimensional stacked nonvolatile semiconductor memory according to an example of the present invention includes a memory cell array comprised of first and second blocks. The first block has a first cell unit which includes a memory cell to be programmed and a second cell unit which does not include a memory cell to be programmed, and programming is executed by applying a program potential or a transfer potential to word lines in the first block after the initial potential of channels of the memory cells in the first and second cell units is set to a plus potential. In the programming, the program potential and the transfer potential are not applied to word lines in the second block.
