Samsung is taking a bigger slice of its own Galaxy S25 memory pie, boosting its LPDDR5X RAM supply share to 60% while cutting Micron’s role to 40%. Just months ago, the Korean tech giant leaned heavily on Micron-tasking it with 60% of the S25’s RAM production-because Samsung’s own 10nm fifth-gen (1b) process was struggling with poor yields and heat issues.
Those hurdles meant Samsung’s Device Solutions division couldn’t meet the MX division’s sample bidding deadline, forcing more reliance on the U.S. supplier.
Now, reports suggest Samsung has solved its yield and thermal problems, revitalizing its memory production capacity. With improved output, the company has taken back the majority share for the S25 series, leaving Micron with a smaller-though still significant-slice of the business. Based on projections, around 22.2 million Galaxy S25 units will ship with Samsung-made LPDDR5X RAM, while Micron will supply roughly 14.8 million units.
Analysts speculate the decision is also tied to stronger S25 sales compared to the S24 lineup. While Micron’s share has shrunk, the company remains a crucial backup supplier-40% of a core component is nothing to dismiss-and it’s likely this ratio will hold for the Galaxy S26 launch next year. Even with its production woes apparently behind it, Samsung is keeping a contingency plan in place, mindful of how quickly the semiconductor market can swing.
