Macronix currently owns a 12″ wafer fab and an 8″ wafer fab; the 6″ wafer fab was sold to Hon Hai in August 2021 for NTD 2.52 billion.

In a recent development of Macronix’s 3D NAND Flash product, mass production of its internally developed 96-layer 3D NAND flash memory has begun, marking a milestone for the chipmaker’s NAND business.

In addition to this, Macronix has previously stated that it expects to complete further development of its 192-layer 3D NAND Flash product by the end of 2023, Macronix’s 48-layer 3D NAND Flash product will be in mass production in September 2021.

In December last year, Macronix’s Board of Directors approved a NT$2.648 billion capital budget for 3D NAND Flash development and operations, including capital expenditures for 2023 and 3D NAND Flash R&D machinery and equipment, which is expected to be invested from the first quarter of 2023.

Macronix is also continuing to advance its serial flash technology and started mass production of its 45nm 3V serial flash series in January this year.
