Comments
As the future entity will be (re)named Spansion, it is worth closing the loop on a story that spans more than three decades.
The original company dates back to 1993, when AMD and Japan's Fujitsu created a joint venture called FASL LLC, derived from Fujitsu AMD Semiconductor Limited.
Around 2003–2005, AMD took control of the business, which was subsequently renamed Spansion and officially spun off as an independent flash memory company in December 2005.
A decade later, in 2015, Cypress Semiconductor merged with Spansion, effectively bringing the Spansion business under the Cypress umbrella. The story continued in 2020 when Infineon Technologies acquired Cypress Semiconductor, adding the former Spansion technologies and product portfolio to its own semiconductor operations.
The circle is now closing once again. Following the completion of this latest acquisition, Winbond plans to revive the Spansion name for the acquired entity, bringing back a brand with roots stretching all the way to the AMD-Fujitsu joint venture created in 1993.
