Samsung Galaxy S25 doesn't use in-house RAM, storage chips

Before the Galaxy S25 series was launched, it was rumored that Samsung might not use its in-house DRAM and storage chips in its new high-end phones. Now, it has been confirmed that the information was correct.

Galaxy S25 uses Micron's DRAM and UFS 4.0 storage chips

Micron, an American memory chip maker, has confirmed that the Galaxy S25, Galaxy S25+, and Galaxy S25 Ultra use its LPDDR5X DRAM and UFS 4.0 storage chips. The company posted this information on X, and it was confirmed by Samsung's smartphone division. Micron is one of Samsung's primary rivals in the semiconductor memory chip segment.

The American firm said that its LPDDR5X DRAM chips are made using the advanced 1β (1-beta) process technology and have design optimizations, enabling them to run at lower voltage levels than competing chips. This results in improved battery life on devices that use those chips.

This might be the first time Samsung has bought memory chips from an outside brand for its flagship smartphones. All previous Galaxy S and Galaxy Z series phones have used Samsung Semiconductor's DRAM and storage chips, so this is a major blow to Samsung's memory chip business.

Mark Montierth, corporate vice president and general manager of Micron’s Mobile Business Unit, said, “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.“
