Taiwan's Winbond Electronics is buying Infineon Technologies' NOR flash and F-RAM business for US$1.12 billion in cash, a deal announced on September 16, 2026 that will revive the fabled Spansion brand and hand the Taiwanese memory maker outright leadership in the code-storage market.
All-Cash Carve-Out
Under the agreement, Winbond acquires 100% of the equity of Infineon's specialty memory division and folds it into a new standalone entity headquartered in San Jose, California. The purchase price of US$1.12 billion is subject to customary adjustments and closing conditions, with completion targeted for the second half of 2027 after regulatory approvals. The business will operate under a resurrected "Spansion" brand — a nod to the memory pioneer whose NOR flash IP still underpins the assets Infineon is divesting.
Global Share Above 30%
According to TrendForce, the transaction could push Winbond's global NOR flash market share above 30%, widening its lead over Macronix and GigaDevice. The acquired unit brings more than 30 years of NOR flash and ferroelectric-RAM engineering, an established design team across San Jose and Munich, and long-standing automotive, industrial and IoT customer relationships that will complement Winbond's TrustME secure flash portfolio.
Infineon Sharpens Its Core
For Infineon, the sale caps a strategic pivot toward power semiconductors, microcontrollers and automotive silicon — areas where the Munich-based company sees deeper long-term growth alongside AI infrastructure and electrification demand. Chairman Arthur Yu-Cheng Chiao said Winbond is "excited to bring back the Spansion company name and trademark," calling Spansion "a pioneer of the industry" whose innovations helped shape modern non-volatile memory.
Why It Matters
NOR flash sits at the intersection of automotive, industrial and edge-AI markets, where secure boot, over-the-air updates and low-latency code storage have become mission-critical. Consolidating Infineon's assets under Winbond concentrates that supply base at a moment when tariff-driven reshoring is reshaping global memory logistics — and creates a rare US-headquartered specialty-memory operator with Taiwanese fab backing.
