Report: TSMC considering expansion into advanced AI memory chip manufacturing

On November 7, 2026, TBS CROSS DIG with Bloomberg reported, citing The Information, that TSMC is considering expanding its business into manufacturing advanced AI memory chips.

Reports that TSMC is considering manufacturing advanced AI memory could signal a potential expansion of the products it makes if the plan moves forward. However, what has been reported so far is only that the company is considering it; the start of manufacturing and any impact on supply volumes have not been confirmed.

The focus of the report is that TSMC is considering manufacturing advanced AI memory chips as an option for expanding its business. However, the report describes a consideration, not a decision to start manufacturing or invest. Assessing the business significance will depend on whether the plan advances, what types of memory it would cover and how the company envisions dividing responsibilities with its existing manufacturing operations. The reported information does not establish these specifics, production scale or timing, so it is not possible at this stage to assess the impact on supply or the market. On August 12, 2026, we reported that Sony Semiconductor Solutions and TSMC had signed a definitive agreement to establish a joint venture in Kumamoto, with plans to contribute a total of about ¥747 billion in stages and begin mass production of image sensors for smartphones in 2029 (Sony and TSMC to establish joint venture in Kumamoto, invest ¥747 billion in total and begin sensor production in 2029). The products and business stages involved differ from those in the report about considering advanced AI memory. The two should therefore not be treated as parts of a single investment plan. At the same time, when tracking TSMC’s manufacturing activities, it is important to distinguish the sensor mass-production plan from the consideration of memory manufacturing, which has not been finalized. If memory manufacturing takes shape, one issue will be how memory is handled in the semiconductor manufacturing process. The report alone does not establish whether TSMC is considering manufacturing it in-house, how it would connect with existing manufacturing operations or how extensively it would be involved in the supply structure for AI chips. The report of a consideration should not be read as confirmation that product supplies will begin or that the effort will be integrated with existing businesses. What to watch next is whether TSMC turns its consideration into a formal plan and whether it discloses the types of memory involved, investment, production capacity and start-up timing. Without details on manufacturing processes and the division of business roles, the relationship with existing manufacturing plans and the implications for supply also remain unclear. For now, it is appropriate to distinguish the reported consideration from a plan that has been put into action.
