Usually, Samsung's phones, tablets, and laptops use in-house RAM and storage chips. However, it was reported that the company could use DRAM chips from other brands in the Galaxy S25, at least for the initial batch.
However, that seems to be changing, as some units might use Samsung's improved in-house memory chips.
Some Galaxy S25 units could use Samsung's improved LPDDR5X RAM chips
According to a report from ETNews, most Galaxy S25 units will use Micron's LPDDR5X DRAM chips. Some units will use Samsung's LPDDR5X DRAM chips, but they will be built using a new technology.
Unlike LPDDR5X DRAM chips used in the Galaxy S24 series, the ones in the Galaxy S25 series will be fabricated on Samsung's 12nm process node instead of 13nm. This will likely result in improved power efficiency and consume less space.
When the company switched from 13nm to 12nm process, there were reportedly a few issues, which delayed the mass production and supply. However, Samsung seems to have resolved those issues and has already increased the pace of chip production.
Samsung could have a larger share of DRAM chip supply compared to Micron in the batches that will be assembled in the later stages.
All three phones in the Galaxy S25 series will reportedly use Qualcomm's Snapdragon 8 Elite chip. Samsung had allegedly planned to use the Exynos 2500 chip in some Galaxy S25 and Galaxy S25+ units, but lower yield forced the company to stick to Qualcomm.

Galaxy S25 RAM and storage
The Galaxy S25 and the Galaxy S25+ reportedly feature 12GB RAM for all their storage variants. The Galaxy S25 Ultra is said to have 12GB RAM for the 256GB storage variant and 16GB RAM for the 512GB and 1TB variants. All these devices will likely have UFS 4.0 storage.
