SK Hynix has just announced the successful development of a 16Gb LPDDR6 DRAM memory product based on its sixth-generation 10nm (1c) process technology, designed to meet the stringent requirements of edge AI applications for high performance and high energy efficiency.
Following its debut at CES in January, SK Hynix has now completed the development and verification of the world’s first 1c process LPDDR6. The company plans to complete mass production preparations in the first half of this year and officially start supplying in the second half, further expanding its conventional DRAM product line optimized for AI applications.
Note: LPDDR (Low Power Double Data Rate) is a DRAM standard used in mobile devices such as smartphones and tablets, characterized by low-voltage operation to minimize power consumption. The LPDDR standard has previously evolved through LPDDR1, 2, 3, 4, 4X, 5, 5X, and now LPDDR6.
SK Hynix Breakthroughs in both performance and energy efficiency
Compared to existing LPDDR5X products, 1c LPDDR6 offers significant improvements in both data processing speed and power consumption. Thanks to expanded bandwidth and increased data transfer rate per unit time, its data processing speed is 33% faster than the previous generation. Its base operating speed exceeds 10.7 Gbps, surpassing the highest speed levels of existing products.
In terms of power consumption, SK Hynix has reduced the power consumption of its new generation of products by more than 20% compared to the previous generation by applying sub-channel architecture and DVFS (Dynamic Voltage and Frequency Scaling) technology.
The sub-channel architecture selectively activates only the necessary data paths, while DVFS technology dynamically adjusts voltage and frequency according to the chip’s operating environment. In high-performance scenarios such as high-specification gaming, devices can increase the DVFS level to obtain maximum bandwidth performance; while in daily use, the frequency and voltage are reduced to save power.
