Samsung Might Equip Galaxy S26 with Enhanced LPDDR5X RAM

Samsung is developing its next-generation flagship smartphone lineup, the Galaxy S26 series. Undoubtedly, like its predecessor, the Korean firm will use LPDDR5X DRAM chips in the flagship models. While LPDDR5X is already capable of high-speed data transfer, Samsung will reportedly integrate an improved version, which may further enhance performance.

Samsung is testing Micron’s improved LPDDR5X samples for the Galaxy S26 series

The Galaxy S25 series uses DRAM chips from both its own memory division and Micron, a third-party memory supplier. According to a report from DealSite, Micron supplies around 60% LPDDR5X chips while Samsung’s Device Solutions (DS) division delivers the remaining 40%. Industry watchers say that Samsung has chosen Micron as the key supplier, likely for its superior manufacturing yields, thermal performance, and power efficiency.

The publication also says that Samsung has begun testing an improved version of Micron’s LPDDR5X sample, likely for the Galaxy S26 series. It features a slightly reduced circuit line width compared to the one used for the Galaxy S25. This change will increase the number of dies produced per wafer by about 15%.

With this change, we can expect faster processing speeds and lower power consumption. For the Galaxy S25 series, Samsung required LPDDR5X memory to support a data transfer speed of at least 9.6 Gbps. The Korean firm might be aiming for even higher speeds with the Galaxy S26 lineup.

If the improved Micron LPDDR5X sample passes the Mobile eXperience (MX) division’s tests, Micron may once again become the key DRAM supplier for the 2026 flagships. Meanwhile, there’s chatter that Samsung may introduce a 16GB RAM configuration across all Galaxy S26 models. If true, the base S26 model could be a solid choice for power users as well, as the increased memory will improve performance and multitasking capabilities. Expect more leaks about these devices in the coming months.
