Micron Technology, Inc. is an American multinational semiconductor company that designs and manufactures computer memory and data storage products, including dynamic random-access memory (DRAM), flash memory, High Bandwidth Memory (HBM), and solid-state drives (SSDs). Founded in 1978 in Boise, Idaho, Micron is the only major American computer memory manufacturer and is one of the "Big Three" memory producers alongside South Korea's Samsung Electronics and SK Hynix. The company markets consumer products under the Crucial brand and has become a key supplier for Artificial intelligence hardware, particularly through its HBM chips used in Machine learning accelerators.
Micron's history is marked by strategic acquisitions, technological innovations in memory fabrication, and leadership transitions. As of 2026, Sanjay Mehrotra serves as president and CEO, a role he has held since 2017. In May 2026, Micron became the latest U.S. company to reach a US$1 trillion market capitalization, driven by surging demand for its HBM products used in AI data centers.
Founding and Early Years (1978-1999)
Micron was founded in Boise, Idaho, in 1978 by Ward Parkinson, Joe Parkinson, Dennis Wilson, and Doug Pitman as a semiconductor design consulting company. Initial funding came from local Idaho businessmen Tom Nicholson, Allen Noble, Rudolph Nelson, and Ron Yanke, with later support from Idaho billionaire J. R. Simplot, whose fortune originated in the potato business. In 1981, the company transitioned from consulting to manufacturing with the completion of its first wafer fabrication unit, Fab 1, producing 64K DRAM chips. The company held its initial public offering in 1984.
In 1991, Micron attempted to enter the RISC processor market with a product called FRISC, targeting embedded control and signal processing. The 80 MHz processor was described as "a 64-bit processor with fast context-switching time and high floating-point performance," supporting timely interrupt handling and featuring an arithmetic unit capable of 80 MFLOPS for double-precision operations. Micron aimed to provide a "board-level demonstration supercomputer" with 256 MB or 1 GB of RAM. Despite setting up a subsidiary and designing the product into graphics cards, Micron concluded in 1992 that the effort would not deliver the "best bang for the buck," reassigning engineers and discontinuing the project.
In 1994, founder Joe Parkinson retired as CEO, and Steve Appleton assumed the roles of Chairman, President, and CEO. A 1996 three-way merger among ZEOS International, Micron Computer, and Micron Custom Manufacturing Services (MCMS) expanded the company's scope, followed by the 1997 acquisition of NetFrame Systems to enter the mid-range server industry. Between 1998 and 2000, Micron sponsored the MicronPC Bowl, a college football bowl game.
Technological Innovations and Expansion (2000-2010)
In 2000, Gurtej Singh Sandhu and Trung T. Doan at Micron initiated development of atomic layer deposition high-k films for DRAM memory devices, which helped drive cost-effective implementation of semiconductor memory starting with 90 nm node DRAM. Sandhu also pioneered pitch double-patterning during the 2000s, leading to 30-nm class NAND flash memory, a technique later widely adopted by NAND and RAM manufacturers worldwide.
In 2002, Micron spun off its personal computer business as MPC Corporation, finding the business difficult as the number 12 American computer maker with only 1.3 percent market share. In 2005, Micron and Intel created a joint venture, IM Flash Technologies, based in Lehi, Utah, to produce NAND flash memory. A second joint venture, IM Flash Singapore, was formed in 2011, with Micron becoming sole owner in 2012. In 2006, Micron acquired Lexar, an American manufacturer of digital media products.
Leadership changed in June 2007 when COO Mark Durcan became president. In 2008, Micron converted the Avezzano chip fab in Italy, formerly a Texas Instruments DRAM facility, into a production site for CMOS image sensors sold by Aptina Imaging. That year, Micron spun off Aptina Imaging, which was later acquired by ON Semiconductor in 2014. The core company faced setbacks, laying off 15 percent of its workforce in October 2008 and announcing the purchase of Qimonda's 35.6 percent stake in Inotera Memories for $400 million. Layoffs continued in 2009 with an additional 2,000 employees terminated, alongside the acquisition of FLCOS microdisplay company Displaytech. In February 2010, Micron agreed to buy flash-chip maker Numonyx for $1.27 billion in stock.
Leadership Transition and Acquisitions (2012-2016)
On February 3, 2012, CEO Steve Appleton died in a plane crash shortly after takeoff from Boise Airport; he was the pilot and sole occupant of the Lancair IV aircraft. Mark Durcan replaced Appleton as CEO, eliminating his former title of president. In 2013, the Avezzano chip fab was sold to LFoundry.
Between 2012 and 2014, Micron underwent another acquisition-layoff cycle, becoming the majority shareholder of Inotera Memories, purchasing Elpida Memory for $2 billion, and acquiring the remaining shares in Rexchip, a PC memory chip venture, for $334 million, while announcing plans to lay off approximately 3,000 workers. The Elpida acquisition made Micron a major supplier to Apple for the iPhone and iPad. In December 2016, Micron completed the acquisition of the remaining 67 percent of Inotera, making it a fully owned subsidiary.
Recent Developments and AI Era (2017-Present)
In April 2017, Micron announced Sanjay Mehrotra as the new president and CEO, replacing Mark Durcan. In June 2017, Micron discontinued the Lexar retail removable media storage business, and in August 2017, the Lexar brand was acquired by Longsys, a Shenzhen-based flash memory company.
In May 2018, Micron and Intel launched QLC NAND memory to increase storage density. The company ranked 150th on the Fortune 500 list of largest U.S. corporations by revenue that year. In February 2019, Micron announced the first microSD card with 1 terabyte (TB) storage capacity. As of March 2020, the 3.84TB Micron 5210 Ion was the cheapest large-capacity SSD in the world. In September 2020, Micron introduced the world's fastest discrete graphics memory solution, GDDR6X, developed with NVIDIA and debuted in the Nvidia GeForce RTX 3090 and RTX 3080 GPUs. In November 2020, the company unveiled a 176-layer 3D NAND module.
Micron's role in Artificial intelligence has grown significantly. Its High Bandwidth Memory (HBM) chips are critical components in AI accelerators used for Deep learning and Large language model training and inference. The company supplies memory for systems from major cloud providers like Amazon Web Services, Microsoft Azure, and Google Cloud, as well as for AI hardware from AMD, Intel, and NVIDIA. In May 2026, Micron reached a US$1 trillion market capitalization, reflecting the surging demand for its HBM products in AI data centers.
