Samsung to Use Improved LPDDR5X Memory in Galaxy S25 Series

Samsung is reportedly set to use its improved LPDDR5X DRAM chips in some units of the Galaxy S25 series.

While most units are expected to feature Micron’s LPDDR5X DRAM chips, some models will utilize Samsung’s in-house chips, which will be fabricated using a 12nm process node—a step up from the 13nm process used in the Galaxy S24 series.

This change is expected to improve power efficiency and reduce the space consumed by the chips.

Production Delays and Supply Changes

Although there were initial delays in production due to issues when switching to the 12nm process, Samsung has reportedly resolved these problems and ramped up chip production.

As a result, the company could secure a larger share of the DRAM chip supply in the later stages of Galaxy S25 assembly.

Galaxy S25 Series RAM and Storage

The Galaxy S25 and Galaxy S25+ are expected to come with 12GB of RAM across all storage variants, while the Galaxy S25 Ultra will feature 12GB of RAM in the 256GB storage variant and 16GB of RAM for the 512GB and 1TB variants. All devices are also likely to feature UFS 4.0 storage for faster data transfer speeds.

Snapdragon 8 Elite Chip

All three models in the Galaxy S25 series will be powered by the Qualcomm Snapdragon 8 Elite chip.

Initially, Samsung had planned to use its Exynos 2500 chip in some models, but due to lower yield, the company opted to stick with Qualcomm for all variants.
