SK Hynix Unveils UFS 4.1 Storage with 321-Layer NAND for Mobile AI

SK Hynix has announced the development of a UFS 4.1 storage solution that leverages a record-breaking 321-layer, 1 terabit triple level cell 4D NAND flash, specifically designed for mobile devices. This advancement addresses mounting demands for higher performance and energy-efficient NAND solutions that support stable operation of on-device Artificial Intelligence. As smartphones increasingly integrate Artificial Intelligence workloads, the new solution is expected to fortify SK Hynix´s position as a leader in the memory market for flagship mobile devices.

One highlight of the newly launched UFS 4.1 product is its significant boost in both power efficiency and compactness. The memory solution delivers a 7 percent improvement in power efficiency compared to its predecessor, which utilized 238-layer NAND technology. Additionally, the new module is only 0.85 mm thick, down from the previous 1 mm design, making it better suited for integration into ultra-slim mobile devices where every millimeter counts.

This product evolution comes as the balance between computational power and battery life emerges as a critical factor for modern smartphones equipped with advanced Artificial Intelligence capabilities. By meeting the mobile market’s need for thinner and more power-conscious designs, SK Hynix’s 321-layer NAND solution not only boosts device performance but also helps manufacturers deliver sleeker, longer-lasting products to consumers demanding ever-greater levels of on-device intelligence and efficiency.
