The Korea Economic Daily reports that Apple and Samsung officially signed an agreement that will see the two companies working together on future A-series chips for Apple’s iOS devices, with the deal specifically covering A9 chips based on a 14-nanometer process node starting in 2015. The claim comes just weeks after Taiwan Semiconductor Manufacturing (TSMC) confirmed a deal with Apple to begin producing A-series chips in 2014. A previous report about Apple’s agreement with TSMC had indicated that it was a three-year deal covering not only Apple’s future A8 chip but also A9/A9X chips. The Wall Street Journal’s report had indicated that Samsung would remain Apple’s primary supplier through next year as TSMC began ramping up its production. As a result, it is unclear whether today’s deal will see both TSMC and Samsung producing A9 chips for Apple or if Apple has already shifted gears to return to Samsung as its primary supplier as part of its long-term roadmap.
