Today, Micron announced the launch of the world's first G9-based UFS4.1 and UFS3.1 storage solutions for smartphones, enabling more on-device artificial intelligence functions. The new memory chips will be launched on flagship products shortly after Micron's 1yLPDDR5X chips become available in early 2026.

UFS4.1 and UFS3.1 mobile memory chips are based on Micron's G9 process node and have higher energy efficiency and read and write speeds. The chips have capacities between 256GB and 1TB and are suitable for ultra-thin and foldable smartphones.

However, in addition to hardware improvements, Micron also promised to make some software adjustments to enhance the user experience and improve the performance of some artificial intelligence tasks. 

For example, the UFS4.1 storage solution supports ZonedUFS, which improves read and write efficiency and reduces write amplification, while data defragmentation improves data relocation and defragmentation within UFS devices by 60%. PinnedWriteBooster can increase the speed of data access in the WriteBooster buffer by 30%. Smart Latency Tracker automates debugging by analyzing latency logs. The last feature also applies to UFS3.1, while the others appear to be unique to the UFS4.1 chip.
