Micron proudly announced that its LPDDR5X DRAM and UFS 4.0 storage chips power the Galaxy S25, S25+, and S25 Ultra. Samsung’s smartphone division backed the claim, marking a shift in the company’s hardware strategy.

Micron’s cutting-edge 1β (1-beta) process technology reportedly delivers lower voltage consumption, enhancing battery life—a key selling point for flagship devices. The company boasts that its high-bandwidth LPDDR5X memory and advanced UFS 4.0 storage accelerate real-time AI processing, allowing consumers to experience AI at their fingertips. Its storage solutions offer high capacities, enabling users to store data locally rather than relying on the cloud, providing greater security for personal information.

Micron’s Mobile Business Unit corporate vice president and general manager Mark Montierth said: "“We’ve optimised Micron’s mobile portfolio to deliver the power efficiency, high performance and large capacity needed to propel the next wave of AI innovation in flagship smartphones."

"Samsung is setting a new standard for AI phones, enabling them to be true AI companions with context-aware and personalized mobile experiences powered by Micron’s leadership memory and storage,” he said.

Samsung has framed the move as part of a bold push into AI-powered mobile technology.

Samsung technology strategy team vice president and head Inkang Song sang: "“The Galaxy S25 series represents the next evolution of the mobile AI era — one that brings a more natural, context-aware and personalized experience to users, redefining how they interact with their devices and by extension, the world around them.”

“Through our close collaboration, Micron’s mobile solutions provide the foundation that powers these transformative AI capabilities, driving innovation and shaping the future of mobile AI technology.”

However, this shake-up is a blow to Samsung’s semiconductor business, which has traditionally supplied memory chips for all Galaxy S and Galaxy Z series devices. Industry insiders are left wondering if Samsung lost faith in its own chip-making capabilities.
