MathStar was an American, fabless semiconductor company based in Oregon. Founded in Minnesota in 1999, the company moved to the Portland metropolitan area where it remained until it completed a reverse merger with Sajan, Inc. in 2010. MathStar never made a profit after raising $137 million over the lifetime of the company, including via several stock offerings while the company was publicly traded on the NASDAQ market. The company’s only product was a field programmable object array (FPOA) chip. ==History== Bob Johnson and Douglas Pihl started discussing the formation of a company in 1999 to design a new type of digital signal processors (DSP) microprocessor chip, and founded MathStar the next year and began raising funds. The two founded the company in Minneapolis, Minnesota, and raised $18 million for the venture by September 2000 when they had grown to approximately 15 employees.〔 MathStar’s new processor was to be based on using a series of algorithms developed by Johnson that were imprinted directly into the processor.〔 In 2002, the company raised another $15.3 million in capital followed by $6 million in 2003. At one point in 2003 the company planned to merge with Digital MediaCom as MathStar still worked to finish developing its chip.〔 MathStar first started producing its processor in 2003, but technical problems led to additional design changes with hopes to restart production in April 2004 after raising an additional $10 million. In May 2005, the company announced plans for an initial public offering (IPO) in hopes of securing $28 million for the then Minnetonka-based company. The company then priced the offering at $6 per share in October of that year with the plan of selling 4 million shares on the Nasdaq market under the ticker symbol MATH. MathStar hoped to raise $21 million at that point to pay down debt and fund research.〔 The company then held the IPO in October 2005 and raised $24 million.〔 MathStar opened an office in Oregon in May 2005 and announced in December that year they would move company headquarters to Hillsboro, Oregon, to have better access to microprocessor talent in the area’s Silicon Forest. The company already had 22 employees there at the time, but planned to keep an office in Minnesota as well.〔 At that time the company’s market capitalization valued the company at $93 million.〔 MathStar officially relocated to Hillsboro in March 2006 from Plymouth, Minnesota. At that point MathStar had 35 employees in Hillsboro with plans to hire 15 more.〔 In early 2006 the company’s auditors raised concerns over MathStar’s ability to continue as a going concern, with the company announcing they would raise more funds to address the issue. MathStar raised an additional $12.6 million by selling stock and warrants in September 2006, and used part of the proceeds to increase staffing to 56 people. At that time, the company also finished its first run of production of its chips using Taiwan Semiconductor Manufacturing Company as the contract manufacturer.〔 MathStar announced in February 2007 that they were working with Mentor Graphics on the design tools for MathStar’s field programmable object array (FPOA) chip. A few months later the fabless semiconductor company announced that for fiscal year 2006 revenues totaled $53,000 and lost $22.5 million. The company announced they would sell another $40 million in stock in March 2007. On May 10, 2007, they announced the company only had enough operating capital to stay in business until Labor Day, and that to raise funds they would sell another $25 million in stock. Sales executive Glen R. Wiley then left the company that month. Later that month, the NASDAQ stock market sent notice to MathStar that it could be delisted from the stock exchange due to equity requirements for stockholders. In early June 2007 MathStar again sold stock to raise $25 million, followed by another offering later that month in an attempt to raise $4.6 million. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MathStar」の詳細全文を読む スポンサード リンク
