Macronix International Co., Ltd. (MCIX; often shortened to Macronix) is an integrated device manufacturer in the non-volatile memory (NVM) market. The company manufactures NOR Flash, NAND Flash, and ROM products for the consumer, communication, computing, automotive, and networking markets. Its headquarters are located in Taiwan.

## History

Headquartered in Taiwan, Macronix was established in 1989. By 1997, the company was a global supplier of Mask ROM and EPROMs.[1]

In 2012 the company developed a process to prolong the life of solid state drives.[2]

Macronix developed specialized memory chips for the consumer electronics industry, including those used in Nintendo's 3DS and Switch devices,[3] and Samsung's wearable electronic devices.[4]

The company presently has more than 4,000 employees—approximately one-fifth of whom serve in research and development roles. Macronix's total revenues in 2023 were US$888 million, slightly more than one-half of which was derived from NOR flash, followed by ROM revenues at approximately one-third.

As of March 2024, Macronix has had 9,200 patents granted.

Macronix owns two in-house wafer-manufacturing foundries—one for 200-nanometer wafers, the other for 300-nanometer wafers. The company also has sales and support branches in Europe, the United States, Japan, Korea, Singapore, and China.

Recognizing the market opportunity in proprietary semiconductor designs becoming high-volume, open-market flash memory, Macronix leveraged flash memory customized for specific customers into widely available devices for broader applications.[5]

Macronix has developed partnerships with various microcontroller manufacturers to pair its OctaBus flash memory with the partners’ MCUs.[6]

In the automotive market, Macronix's automotive-grade ArmorFlash and OctaFlash memory families are being adopted by automotive-electronics semiconductor and system makers such as Nvidia and NXP to bring highly secure data storage to vehicles.[7][8][9]

In 2021, Macronix became the first NVM manufacturer to bring 1.2-volt, 120 MHz Serial NOR flash to mass production, contributing to a new generation and broader range of devices requiring ultra-low-power flash memory.[10][11]

Macronix in 2022 introduced its memory-centric computing concept, developed to enable AI-focused computation within flash devices.[12][13] Also in 2022, Macronix received EE Times Asia's Best Memory Product award for the second consecutive year.[14]
