Micron was founded in Boise, Idaho, in 1978[5] by Ward Parkinson, Joe Parkinson, Dennis Wilson, and Doug Pitman as a semiconductor design consulting company.[6] Startup funding was provided by local Idaho businessmen Tom Nicholson, Allen Noble, Rudolph Nelson, and Ron Yanke. Later it received funding from Idaho billionaire J. R. Simplot, whose fortune was made in the potato business. In 1981, the company moved from consulting to manufacturing with the completion of its first wafer fabrication unit ("Fab 1"), producing 64K DRAM chips.

In 1994, founder Joe Parkinson retired as CEO and Steve Appleton took over as Chairman, President, and CEO.[5]

A 1996 3-way merger among ZEOS International, Micron Computer, and Micron Custom Manufacturing Services (MCMS) increased the size and scope of the company;[5] this was followed rapidly with the 1997 acquisition of NetFrame Systems, in a bid to enter the mid-range server industry.[7]


In 2000, Gurtej Singh Sandhu and Trung T. Doan at Micron initiated the development of atomic layer deposition high-k films for DRAM memory devices. This helped drive cost-effective implementation of semiconductor memory, starting with 90-nm node DRAM.[8][9] Pitch double-patterning was also pioneered by Gurtej Singh Sandhu at Micron during the 2000s, leading to the development of 30-nm class NAND flash memory, and it has since been widely adopted by NAND flash and RAM memory manufacturers worldwide.[8][10]

Micron and Intel created a joint venture in 2005, based in IM Flash Technologies in Lehi, Utah.[11] The two companies formed another joint venture in 2011, IM Flash Singapore, in Singapore.[12] In 2012, Micron became sole owner of this second joint venture.[13]

In 2006, Micron acquired Lexar, an American manufacturer of digital media products.[3]

The company again changed leadership in June 2007 with COO Mark Durcan becoming President.[14]

In 2008, Micron spun off Aptina Imaging, which was acquired by ON Semiconductor in 2014. Micron retained a stake in the spinoff.[15] The core company suffered setbacks, however, requiring layoffs of 15 percent of its workforce in October 2008,[16][17] during which period the company also announced the purchase of Qimonda's stake in Inotera technologies for $400 million.[18] The trend of layoffs and acquisitions continued in 2009 with the termination of an additional 2,000 employees,[19][20] and the acquisition of the FLCOS microdisplay company Displaytech.[21] Micron agreed to buy flash-chip maker Numonyx for $1.27 billion in stock in February 2010.[22]

On February 3, 2012, the CEO, Steve Appleton, died in a small Lancair plane crash in Boise, Idaho.[23][24][25] Mark Durcan replaced Appleton as the CEO shortly thereafter,[26] eliminating his former title of President.[27]

In the 2012–2014 period, Micron again went through an acquisition-layoff cycle, becoming the majority shareholder of Inotera Memories, purchasing Elpida Memory and Powerchip,[28] while announcing plans to lay off approximately 3,000 workers.[29][30]

In December 2016, Micron finished acquiring the remaining 67% of Inotera’s stake and made Inotera a 100% subsidiary of Micron in Taiwan.[31]

In April 2017, Micron announced Sanjay Mehrotra as the new President and CEO to replace Mark Durcan.[32][33]

In June 2017, Micron announced it was discontinuing the Lexar retail removable media storage business and putting some or all it up for sale.[34] In August of that year the Lexar brand was acquired by Longsys, a flash memory company based in Shenzhen, China.[4]

In May 2018, Micron Technology and Intel launched QLC NAND memory to increase storage density.[35] The company ranked 150th on the Fortune 500 list of largest United States corporations by revenue.[36]

In February 2019, the first microSD card with a storage capacity of 1 terabyte (TB) was announced by Micron.[37]
