Memory is a key part of artificial intelligence operation on smartphones. Yet we often focus on the processor doing all the work. In reality, even with a good chipset, you’re not going to get fast and seamless experiences if the memory and storage can’t keep up.
Samsung’s Galaxy S25 series is among the Snapdragon 8 Elite’s adopters, which is one of the best on-device processing machines right now. Micron is responsible for the LPDDR5X memory and UFS 4.0 storage supporting its most powerful features, and they’re not shy to brag about it.
Galaxy S25 Series got a brain boost from Micron
A recent press release from Micron Technology announced that Samsung’s Galaxy S25 series uses Micron’s Low Power Double Data Rate 5X (LPDDR5X) memory and Universal Flash Storage (UFS) 4.0 storage. Both components support AI features running directly on the device, which is a major selling point as users demand for more data privacy.
We’ve optimized Micron’s mobile portfolio to deliver the power efficiency, high performance and large capacity needed to propel the next wave of AI innovation in flagship smartphones. Samsung is setting a new standard for AI phones, enabling them to be true AI companions with context-aware and personalized mobile experiences powered by Micron’s leadership memory and storage

Voice assistants, real-time translations, image recognition, and other AI features demand massive computing power. Before on-device AI became feasible, many phones didn’t have the necessary processing speed and memory bandwidth to handle tasks independently.
Instead, they send your commands, photos, or text input to remote cloud servers, where high-performance data centres process the request before sending the results back to your phone. The biggest red flag is that your data has to leave the device at all.
With Micron’s LPDDR5X memory and UFS 4.0 storage bypassing the cloud system, AI responses are faster, battery life improves, and your data is safe. Particularly battery life, the company says power efficiency increases by over 10%. Part of that owes to the 1β (1-beta) process technology running on lower voltages than usual. Each memory cell shrinks and requires less power to store and transfer data.

Cop a Galaxy S25 phone
All phones in the Galaxy S25 series have the LPDDR5X memory and UFS 4.0 storage inbuilt, and that includes the S25, S25+, and S25 Ultra models. The series is widely available for purchase, and the Galaxy S25 comes with 128GB or 256GB of storage, both paired with 8GB of RAM.
The Galaxy S25+ offers 256GB or 512GB of storage, both featuring 12GB of RAM. Meanwhile, the Galaxy S25 Ultra is available in 256GB, 512GB, and 1TB storage options, all paired with 12GB of RAM.
None of the models support expansion via SD cards, so the one you get is what you’re stuck with. On the bright side, there’s six months of free Gemini Advanced and other premium subscriptions waiting for you if you hurry.
