Micron Memory Japan

Micron Memory Japan, K.K. (Japanese: マイクロンメモリジャパン株式会社; Micron Memory Japan Kabushiki-gaisha (MMJ)) is a Japanese subsidiary of Micron Technology. It was formerly known as Elpida Memory, Inc. (エルピーダメモリ株式会社, Erupīda Memori Kabushiki-gaisha) established in 1999 that developed, designed, manufactured and sold dynamic random-access memory (DRAM) products. It was also a semiconductor foundry. With headquarters in Yaesu, Chūō, Tokyo, Japan, it was initially formed under the name NEC Hitachi Memory in 1999 by the merger of the Hitachi and NEC DRAM businesses. In the following year it took on the name Elpida. In 2003, Elpida took over the Mitsubishi DRAM business. In 2004, it listed its shares in the first section of the Tokyo Stock Exchange. In 2012, those shares were delisted as a result of its bankruptcy. In 2013, Elpida was acquired by Micron Technology. On February 28, 2014, Elpida changed its name to Micron Memory Japan and Elpida Akita changed its name to Micron Akita, Inc.

Elpida Memory was founded in 1999 as a merger of NEC's and Hitachi's DRAM operations and began development operations for DRAM products in 2000. Both companies also spun off their other semiconductor operations into Renesas.

In 2001, the company began construction of its 300mm wafer fabrication plant. Later that year, it began sales operations in domestic markets.

In 2002, armed with the Sherman Antitrust Act, the United States Department of Justice began a probe into the activities of dynamic random access memory (DRAM) manufacturers. US computer makers, including Dell and Gateway, claimed that inflated DRAM pricing was causing lost profits and hindering their effectiveness in the marketplace. To date, five manufacturers have pleaded guilty to their involvement in an international price-fixing conspiracy including Hynix, Infineon, Micron Technology, Samsung, and Elpida. Micron Technology was not fined for its involvement due to co-operation with investigators.

In 2003, the company took over Mitsubishi Electric Corporation's DRAM operations and employed Mitsubishi development engineers.

In 2004, Elpida Memory went public and was listed on the Tokyo Stock Exchange.

In 2006, the company established Akita Elpida to take on the development of advanced back-end technology processes.

In March 2006, Elpida reported consolidated sales of 241,500,000,000 Japanese yen. It employed 3196 people.
