What does the "1c process" mean in memory manufacturing and what does it mean for users?

LPDDR6 is built on SK Hynix's 1c (10nm-class) DRAM process — the "c" designation in SK Hynix's nomenclature indicates the third generation of 10nm-class manufacturing (following 1a and 1b). Smaller letter generations mean higher transistor density, enabling smaller chips at the same capacity or greater capacity at the same size with improved efficiency. For end users: the same amount of RAM that is faster and more battery-friendly.

How does a 33% AI speed increase translate to everyday user experience?

Bandwidth-hungry AI tasks will see a 33% speed-up in data processing compared to LPDDR5X — in modern smartphones, on-device AI encompasses real-time photo processing, live video enhancement, speech recognition, instant translation, and sensor data analysis. All these tasks rely on moving massive data volumes between the processor and memory — 33% faster bandwidth means quicker results and smoother responsiveness across every AI-driven feature.

What's the practical difference between Sub-Channel and DVFS in achieving power savings?

The 20% efficiency gain comes from Sub-Channel structure putting unused data paths dormant, and DVFS reducing frequency and voltage for light loads while ramping up for demanding tasks — Sub-Channel is like switching off unused highway lanes to save energy, while DVFS is like reducing engine speed in city driving and increasing it on the motorway. Combining both technologies achieves greater savings than either could deliver alone.

Which upcoming flagship phones will likely be first to feature LPDDR6?

Mass production begins in the second half of 2026 — H2 2026 coincides with major flagship launches: Samsung Galaxy Z Fold8 and Flip8 (expected July-August), Google Pixel 11 Pro Fold (expected August), and iPhone 18 Pro (September). Snapdragon 8 Elite Gen 5 and Apple A20 Pro are the most likely processors to debut with LPDDR6 support — confirmation will come with H2 2026 announcements.

How does SK Hynix compete against Samsung and Micron in the mobile memory market?

SK Hynix completed validation of 1c dies and is now preparing for mass production — the three major players (Samsung, SK Hynix, and Micron) compete in a race toward ever-finer manufacturing processes. Samsung has also previously announced LPDDR6 while Micron works to keep pace. SK Hynix has distinguished itself in recent years through early shipments of advanced DRAM chips — its supply relationships with Apple and Qualcomm give it a strong foothold in premium device memory.

SK Hynix Develops 1cnm LPDDR6: 10.7 Gbps Speed, 33% Faster AI Performance, and 20% Higher Power Efficiency

SK Hynix Develops 1cnm LPDDR6: 10.7 Gbps Speed, 33% Faster AI Performance, and 20% Higher Power Efficiency — Mass Production H2 2026

21/03/2026

SK Hynix Develops 1c-Process LPDDR6 RAM — 10.7Gbps Base Speed, 33% Faster AI Processing, 20% Greater Power Efficiency — Mass Production H2 2026

SK Hynix announced it will start mass production of LPDDR6 memory based on its latest 1c (10nm-class) DRAM process in the second half of this year. The company just completed validation of the 1c dies and will spend the first half of the year in preparation for mass production.

Speed and Performance — 33% Faster AI Data Processing

SK Hynix developed 16 gigabit LPDDR6 chips targeting smartphones and tablets with on-device AI. Bandwidth-hungry AI tasks will see a 33% speed-up in data processing compared to LPDDR5X. The new RAM operates at a base speed of 10.7Gbps.

Power Efficiency — 20% Lower Consumption via Two Complementary Technologies

LPDDR6 is at least 20% more power efficient than the previous RAM standard, achieved through two mechanisms: a sub-channel structure that allows some data paths to go dormant when full bandwidth isn't needed, and DVFS (Dynamic Voltage and Frequency Scaling) that reduces operating frequency and voltage for light loads and ramps them back up for demanding tasks like AI and gaming.

Impact on Future Devices

SK Hynix says its 1c LPDDR6 RAM will enable longer battery life and higher multitasking performance on future devices.
