Infineon Technologies said on 16 September 2026 that it had signed a definitive agreement to sell its NOR Flash and F-RAM memory business to Taiwan-based Winbond Electronics Corporation. The announced transaction is valued at $1.12 billion on a cash-and-debt-free basis. Closing requires regulatory approvals, and the parties target completion in the second half of 2027. The announced value and signed agreement therefore do not mean ownership has already transferred or that Winbond has recorded the sale as completed.

The business to be sold includes NOR Flash and F-RAM products serving automotive, industrial and infrastructure customers. Infineon said Winbond plans to operate the acquired business as a standalone entity headquartered in Silicon Valley in the United States. The agreement could shape the future operating arrangements for those product families, their customers and staff, but the announcement did not specify a transition plan, employee count, geographic sales mix or post-closing brand structure. It also did not describe changes that end customers should expect in the products.

Infineon presented the transaction as part of its strategy to focus its portfolio and capital allocation on core growth areas. It said it will continue to offer specialty memory solutions, including SRAM, HYPERRAM, nvSRAM and SONOS-based radiation-hardened memory. That distinction means the announcement is not a complete exit from all memory activities. Infineon said these retained technologies continue to support applications in automotive, industrial, infrastructure, aerospace and defence markets.

The $1.12 billion amount is stated on a cash-and-debt-free basis; the companies did not publish a detailed payment schedule or closing adjustments. Because completion remains subject to regulatory approvals, the second half of 2027 is a target window rather than a confirmed closing date. Any assessment of the deal should distinguish the expected portfolio change from the conditions that must be met before completion. The release describes strategic intent but gives no quantified forecast for production volumes, customer retention or future profitability effects.

Closing conditions matter because the buyer and seller will need to separate operations while maintaining customer service. The release does not describe workforce-transfer arrangements, supply contracts or transitional licensing that may govern that process. Such details may emerge during regulatory review and closing preparations. What is clear now is that a defined memory portfolio is covered by the sale agreement and that Infineon intends to retain several specialty-memory families.
