Renesas Electronics Corporation (ルネサス エレクトロニクス株式会社 Runesasu Erekutoronikusu Kabushiki Gaisha?) TYO: 6723 is a Japanese semiconductor manufacturer headquartered in Tokyo. It has manufacturing, design and sales operations in around 20 countries.[3] It is one of the world's largest makers of semiconductor systems for mobile phones and automotive applications, the world's largest maker of microcontrollers, and the second largest maker of application processors.[4] It also makes LCD drivers, RF ICs, mixed-signal integrated circuits and system on a chip semiconductors.


"Renesas" is an invented name and a contraction of Renaissance Semiconductor for Advanced Solutions.[5]


Renesas Electronics started operation in April 2010, through the integration of NEC Electronics Corporation and Renesas Technology Corporation. NEC Electronics was established in November 2002 by a spin-off of the semiconductor operations of NEC. Renesas Technology was established on April 1, 2003, as a joint venture of Hitachi, Ltd. (55%) and Mitsubishi Electric (45%).

In April 2009, Renesas Technology and NEC Electronics reached a basic agreement to merge by around April 2010. On April 1, 2010 NEC Electronics and Renesas Technology merged, forming Renesas Electronics which became the fourth largest semiconductor company according to iSuppli published data.

In 2011, Renesas Electronics was adversely affected by the 2011 Tōhoku earthquake and tsunami[6] and flooding in Thailand. In 2012, the company decided to restructure its business, including the sale and consolidation of its Japanese domestic plants, to get profitable.[7][8] In December 2012, INCJ, Japan’s government-backed fund, and several key clients decided to invest in the company.[citation needed] Through the investment, Renesas aimed to secure 150 billion yen as fresh capital by September 2013 and use it for realizing the Smart Society[clarification needed] through investment in the microcontroller and Analog & Power semiconductor development, plant improvements, automotive and industrial semiconductor solutions and corporate acquisitions.[citation needed]

In September 2013, Broadcom acquired Renesas Mobile.[9]

In December 2014, Renesas Electronics introduced 5 new product versions in the RMLV0816B and RMLV0808B series of Advanced Low-Power SRAM (Advanced LP SRAM), the company’s flagship static random-access memory (SRAM) devices.[10]


Renesas Electronics' products include:

At the end of September 2013, Renesas issued new shares through third-party allotment resulting in Innovation Network Corporation of Japan becoming the new largest shareholder and non-parental controlling shareholder.[12]

In early May 2012, NEC transferred part of its stake in Renesas to its employee pension trust. As a result, the NEC pension fund held 32.4 percent of Renesas while NEC had 3.0 percent.[13]
