SK하이닉스, 모바일 기기 온디바이스 AI 성능 향상 위해 16Gb LPDDR6 D램 개발 - Korea IT Times

SK hynix announced that it has successfully developed a 16Gb LPDDR6 DRAM, a next-generation mobile memory product designed to support the growing demand for on-device artificial intelligence (AI). The company said on March 10 that the new memory was developed using its 10-nanometer-class sixth-generation (1c) process technology and has recently completed the necessary certification procedures. SK hynix plans to finalize preparations for mass production in the first half of the year and begin supplying the product to global customers in the second half. LPDDR (Low Power Double Data Rate) is a low-power DRAM standard widely used in mobile devices such as smartphones and tablets. Designed to operate with low voltage, LPDDR memory minimizes power consumption while maintaining high performance. The latest specification in this category is LPDDR6. The newly developed LPDDR6 DRAM is optimized for on-device AI environments, where artificial intelligence processing is performed directly on mobile devices without relying on external servers. This approach allows faster response times and enables more personalized user experiences. Compared with the previous LPDDR5X generation, the new product improves data processing speed by about 33 percent. It achieves a baseline operating speed of more than 10.7 gigabits per second (Gbps), surpassing the maximum performance level of earlier LPDDR generations. Energy efficiency has also been significantly enhanced. By adopting a sub-channel architecture and Dynamic Voltage and Frequency Scaling (DVFS) technology, the new memory reduces power consumption by more than 20 percent compared with the previous generation. The sub-channel structure improves efficiency by selectively activating only the data paths required for specific operations. DVFS technology further optimizes performance and power usage by dynamically adjusting voltage and frequency depending on workload conditions. For example, the system can increase frequency to secure maximum bandwidth during high-performance tasks such as advanced gaming or intensive computing, while lowering power consumption in everyday use to extend battery life. SK hynix expects the new LPDDR6 memory to improve both multitasking performance and battery efficiency in mobile devices. A company official said SK hynix is currently preparing for mass production in line with the requirements of global mobile customers and will continue supplying advanced AI memory solutions to support next-generation on-device AI environments.
