Samsung is giving Micron more Galaxy S25 RAM orders

Samsung’s Galaxy S25 phones won’t be using just Samsung-made memory. In a move that would’ve seemed unlikely a few years ago, the company’s mobile division is giving a bigger share of its RAM orders to Micron, one of its main rivals in the memory market.

Korean reports say Micron will supply around 60% of the LPDDR5X RAM for the Galaxy S25 series. Samsung’s own chip division will supply the remaining 40%. The reason is simple. Samsung Semiconductor is facing lower yields for LPDDR5X chips, which means they cost more to produce. Micron, by contrast, can make them more efficiently, which lowers costs and improves availability.

Micron isn’t stopping at the S25 either. It’s already sending over early LPDDR5X samples for the Galaxy S26 series. These newer chips use a tighter circuit design that could improve yields even further. There’s also a chance Samsung could make 16GB RAM options more widely available on the S26, not just in select markets like before.

For a company that builds everything from memory to displays in-house, shifting key component orders to a competitor says a lot. In the end, performance, cost, and reliability win. Even if it means handing business to someone outside the family.
