Samsung Could Increase Micron’s RAM Supply in Galaxy Flagships

While Samsung has its own memory division, the company also relies on a third-party supplier, Micron, for the RAM in its Galaxy S25 models. This is reportedly due to heat management and production yield issues with its in-house 10nm LPDDR5X memory chips. A fresh report now suggests that the Korean firm may increase the use of Micron memory in flagship Galaxy devices going forward.

Samsung may increase Micron’s RAM supply share to 60%

For the initial few months since the launch of the Galaxy S25 series, Samsung’s MX division relied heavily on Micron for LPDDR5X RAM. The US-based supplier served as the primary memory provider. However, Samsung has recently shaken up the supplier chain, lowering Micron’s share to 40%. On the other hand, the firm has increased the share of its in-house DS division chips to 60%.

Recently, Mizuho TMT specialist Jordan Klein said that Samsung is now considering raising Micron’s share to 60%. In third-quarter pricing discussions, Micron asked for a 10% price hike, and Samsung eventually agreed closer to their terms. This shows the US memory maker now has a stronger position and could secure more business from Samsung in the future.

Earlier this month, a report claimed that the upcoming Galaxy S26 Ultra will feature faster LPDDR5X RAM, offering a data transfer rate of 10.7 Gbps. This is around 25 percent faster than the 8.5 Gbps RAM in Galaxy S25 Ultra. However, the report did not mention whether Samsung’s own chips or Micron’s memory will be used in the new device.

If Samsung’s DS division continues to face yield issues with its memory chips, we can assume the MX division will use a greater share of Micron’s DRAM in its 2026 flagship models. We will learn more about this in the coming months. For now, all eyes are on Samsung’s next-gen Galaxy S flagship lineup, which could include the Galaxy S26 Pro, S26 Edge, and S26 Ultra.
