SK hynix has developed 1c LPDDR6 RAM, which is faster and more efficient than older standards | Infinium-tech
SK Hynix announced that it will begin mass production of LPDDR6 memory based on its latest 1C (10nm-class) DRAM process in the second half of this year. The company has just completed validation of 1C dies and will spend the first half of this year preparing for mass production.
The company has developed 16 gigabit LPDDR6 chips that will be used in smartphones and tablets with on-device AI. Bandwidth-hungry AI tasks will see a 33% speedup in data processing compared to LPDDR5X. The base operating speed of the new RAM is 10.7Gbps.
Additionally, LPDDR6 is at least 20% more energy efficient than the previous RAM standard. This is achieved by two methods that scale performance based on demand: sub-channel structure and DVFS.
The sub-channel structure allows some data paths to remain idle when additional bandwidth is not required. DVFS, or Dynamic Voltage and Frequency Scaling, does exactly what it says on the tin – it lowers the operating frequency (and thus the voltage) for lighter loads and can crank them back up for demanding tasks like AI and gaming.
SK Hynix says its 1C LPDDR6 RAM will enable longer battery life and higher multitasking performance on future devices.
