Semiconductor Technology

Event Summary

Kioxia and Western Digital — Sandisk have announced the commencement of production for their advanced 10th-generation 3D Flash memory technology at the Fab2 (K2) facility located at the Kitakami Plant in Iwate Prefecture, Japan. This milestone is a result of their long-standing joint venture, which was recently extended through December 2034. The K2 facility, which opened in September 2025, has already been producing 8th-generation 3D flash memory products and will now scale up with the new 10th-generation products. Both generations utilize innovative CBA (CMOS directly Bonded to Array) technology, offering high performance, high capacity, and low power consumption. The facility itself boasts an earthquake-absorbing structure, energy-saving equipment, and AI for enhanced production efficiencies. This move aims to address the strong and growing demand for flash memory, especially in the rapidly expanding AI market, and is seen as a significant step for both companies in driving multi-year bit growth and strengthening U.S.-Japan economic relations.
