Samsung has decided to split the initial DRAM supply for its upcoming Galaxy S26 smartphone equally between its own semiconductor division and Micron.
This 50:50 split isn't just a simple sourcing adjustment; it's a direct response to a massive shift in the global memory market, all driven by the AI boom. The core of the issue is that memory manufacturers are prioritizing the production of HBM (High Bandwidth Memory), which is essential for AI servers. Since factory capacity is finite, increasing HBM output means reducing the supply of other memory types, including the LPDDR5X DRAM used in high-end smartphones like the Galaxy S26.
This created a powerful chain reaction. First, the shift to HBM led to a structural shortage of mobile DRAM. This supply squeeze gave memory suppliers, including Samsung's own DS division and competitors like Micron, tremendous pricing power. As a result, the price of a 12GB LPDDR5X module, a key component for the S26, reportedly soared from around $30 to $70 in late 2025. This fundamentally changed the negotiation landscape.
Second, with suppliers in the driver's seat, long-term, fixed-price contracts became a thing of the past. They moved to shorter-term quarterly or even monthly contracts at much higher prices. For Samsung's MX (Mobile eXperience) division, this created huge uncertainty. They could no longer rely solely on their internal DS division, which now had a strong incentive to sell its limited DRAM supply to the highest bidder, such as Apple, which was reportedly willing to accept significant price hikes.
Faced with this dilemma ahead of the S26 launch, the MX division had to act. The unusual meeting between Samsung's mobile chief and Micron's CEO at CES signaled a strategic shift. The 50:50 split with Micron is, therefore, a crucial move to hedge risk and secure a stable supply for the initial production run. It ensures they have enough chips, even if it means paying a premium. Ultimately, this significant increase in component costs, estimated to add over $30 to the bill of materials per phone, makes a consumer price hike for the Galaxy S26 almost inevitable.
