Infineon to sell NOR Flash and F-RAM business to Winbond

Infineon Technologies has entered a definitive agreement to sell its NOR Flash and F-RAM memory business to Taiwan-based Winbond Electronics Corporation, in an all-cash transaction valued at $1.12 billion on a cash and debt free basis. The companies are targeting closing in the second half of 2027, subject to regulatory approvals.

What the business covers

The business being sold comprises Infineon's NOR Flash and F-RAM product lines, which serve customers in automotive, industrial and infrastructure markets. Winbond will operate the acquired business as a standalone entity headquartered in Silicon Valley, according to Infineon.

Infineon states the move allows it to focus its portfolio and capital allocation on core growth areas. Peter Schiefer, President of Infineon's Automotive Division, said the transaction represents a strategic outcome that also enables the NOR Flash and F-RAM business to unlock its full potential; this is an Infineon characterisation of the deal's value rather than an independently verified market assessment.

Retained specialty memory portfolio

Infineon confirms it will continue to offer a portfolio of specialty memory solutions, including SRAM, HYPERRAM, nvSRAM and SONOS-based radiation-hardened memory. The company describes these as remaining important across automotive, industrial, infrastructure, aerospace and defence applications, including high-reliability memory for space missions.

Design engineers and buyers currently specifying Infineon NOR Flash or F-RAM parts should note that ownership of these lines is set to transfer to Winbond following the targeted 2027 closing, while Infineon's remaining memory portfolio is unaffected by this transaction.
