Macronix, a key manufacturer of ROM chips used in Nintendo Switch game cartridges, has announced plans to exit the gaming sector. The company intends to gradually phase out its production of these components as it shifts focus toward more profitable memory technologies.
Shifting Production Priorities
According to the company’s third-quarter earnings report, as noted by the Taiwanese outlet BigGo Finance, Macronix’s ROM chip production “has reached its end.” The manufacturer explained that it is “gradually decoupling from the game industry” to prioritize the production of NOR- and NAND-based memory and eMMCs, which are currently in higher demand.
The company is facing capacity constraints, with its production limited to 25,000 12-inch wafers per month. Because ROM chip production has declined by 39 percent over the past year and now accounts for only 5 percent of the company’s total business, Macronix is reallocating its limited wafer space to more lucrative chip types.
Impact on Nintendo
This strategic shift presents a potential challenge for Nintendo. Analyst David Gibson identified Macronix as the “main memory chip maker” for the company’s physical game cartridges. As Nintendo continues to rely on physical media for the Switch and its upcoming successor, the loss of this primary supplier could complicate supply chain logistics.
While Macronix has announced $1.2 billion in planned investments to expand its manufacturing capacity, the company stated that these new facilities will take at least a year to become operational. In the meantime, the industry-wide demand for memory and storage—driven largely by the artificial intelligence sector—continues to exert pressure on the availability and pricing of various semiconductor components.
