Infineon is divesting parts of its memory business: The chipmaker is selling its NOR flash and FRAM device business to Taiwanese memory specialist Winbond for 1.12 billion U.S. dollars. The division is set to operate independently under the name Spansion starting in 2027.

Infineon has entered into a binding agreement with Winbond for the sale of its NOR flash and FRAM businesses. The Taiwanese memory manufacturer will pay a base purchase price of $1.12 billion, subject to the adjustments provided for in the purchase agreement. The transaction is expected to close in the second half of 2027 and is subject to, among other things, the necessary regulatory approvals.

The transaction includes Infineon’s NOR flash and FRAM portfolio for automotive, industrial, and infrastructure applications. Upon completion, Winbond will acquire, directly or indirectly, all shares in the company established for this purpose. The business will then continue to operate as an independent company headquartered in San José, California.

According to media reports, approximately 350 employees from ten countries will transfer to Winbond as part of the deal, a large portion of whom are based in the United States. This represents an annual revenue loss of approximately 350 million euros ($402.5 million) for Infineon. Winbond expects the acquisition to provide additional development resources and expand its supply and partner network.

The Independent Company Is Once Again Operating Under the Name Spansion

Once the transaction is complete, the company will be named Spansion. The name comes from the flash memory manufacturer Spansion, which merged with Cypress Semiconductor in 2015. With Infineon’s acquisition of Cypress in 2020, the relevant memory portfolio ultimately became part of Infineon. Winbond is thus reverting to a former company name for the spun-off unit.

Operationally, the company is expected to remain independent under Winbond. The acquired NOR flash and F-RAM portfolio complements Winbond’s existing memory offerings. Winbond specifically cites additional research and development resources and expanded supply chain capabilities as the objectives of the transaction.

SRAM, HYPERRAM, and Radiation-Hardened Memory Will Remain with Infineon

Several of Infineon’s specialized memory technologies are not included in the sale. SRAM, HYPERRAM, nvSRAM, and radiation-hardened memory based on SONOS technology will remain within the Group. These devices are used, among other things, in automotive, industrial, and infrastructure applications, as well as in aerospace and defense systems.

Infineon cites a stronger focus of its portfolio and capital allocation on other business areas as the reason for the spin-off. NOR flash and FRAM represent a comparatively small portion of the overall portfolio. Infineon’s focus includes, among other things, power semiconductors and microcontrollers; most recently, the company has also expanded its business with components for AI data centers.

For developers and buyers, the next steps leading up to the planned completion in 2027 are particularly relevant. The announcements released so far do not yet contain any specific details regarding possible changes to product names, roadmaps, manufacturing locations, qualifications, or lifecycle statuses of individual NOR flash and F-RAM devices. What is certain so far is that, following the closing of the transaction, the business will continue as an independent Winbond subsidiary under the name Spansion.
