SK hynix has officially announced a major step forward in mobile memory technology with the successful development of its LPDDR6 DRAM built on the advanced 1c process node (a sixth-generation 10nm-class manufacturing technology). The company says the new 16Gb LPDDR6 is designed to meet the growing demands of on-device AI, where fast data handling and power efficiency matter as much as raw performance.
What makes this announcement especially notable is that SK hynix has now completed what it describes as the world’s first validation of 1c-based LPDDR6 development. After first showing the product earlier this year, the company is moving quickly toward real-world availability: preparations for mass production are expected to wrap up in the first half of the year, with supply planned to begin in the second half.
Built for next-generation smartphones and tablets with on-device AI
LPDDR6 is aimed primarily at mobile devices such as smartphones and tablets, particularly those built to run AI features directly on the device. As more AI tasks shift away from the cloud and onto local hardware—think real-time translation, image generation and enhancement, smarter camera processing, and advanced voice assistants—memory speed and efficiency become critical. Faster memory helps AI models access data quicker, while lower power usage helps keep devices cool and preserves battery life.
Up to 10.7 Gbps speeds, delivering a big performance leap
According to SK hynix, the new LPDDR6 boosts data processing speed by 33% compared to the previous LPDDR5X generation. This jump comes from expanded bandwidth and increased data transmission per unit time. The company lists a base operating speed of over 10.7 Gbps, which is positioned as beyond the maximum speed of existing products in the same category.
In practical terms, higher memory bandwidth can translate into smoother multitasking, faster app launches, improved responsiveness in AI-driven features, and better performance stability in demanding workloads.
More than 20% lower power use for better battery life
Speed is only half the story. SK hynix also emphasizes that power consumption has been reduced by more than 20% versus the previous generation. This comes from a combination of a sub-channel structure and DVFS (Dynamic Voltage and Frequency Scaling) technology.
The sub-channel structure is designed to selectively run only the data paths that are needed, rather than keeping everything active all the time. DVFS, meanwhile, dynamically adjusts frequency and voltage depending on what the device is doing. During intensive activities like high-end mobile gaming or heavy AI workloads, the system can raise performance levels to maximize bandwidth. During everyday tasks, it can scale down frequency and voltage to cut power draw.
For users, this approach is meant to deliver longer battery life without sacrificing the ability to ramp up performance when needed.
Positioned for the next wave of AI-focused mobile hardware
With LPDDR6 on the 1c process, SK hynix is aiming to strengthen its DRAM lineup for AI-optimized devices. The company expects the improvements to benefit consumers through better multitasking and longer usage time between charges, while also helping device makers meet market demand as on-device AI becomes a standard feature in premium mobile products.
SK hynix also says it plans to continue working closely with customers to deliver AI memory solutions on time, focusing on creating differentiated value for users relying on on-device AI features.
