SK hynix said Tuesday it has completed developing low-power double data rate 6 (LPDDR6) memory using the sixth-generation 10-nanometer-class dynamic random access memory technology, called 1c process.
LPDDR is commonly used in smartphones and other portable devices and is designed primarily to minimize power consumption. LPDDR6 represents the eighth generation of the LPDDR standard.
SK hynix said it will complete preparations for mass production within the first half of the year and begin shipping it to clients in the second half, so that it can “establish a general memory product lineup optimized for artificial intelligence (AI) applications.”
The company said its 1c LPDDR6 memory will be used for smartphones and tablet PCs featuring on-device AI functions, leveraging its improved data processing speed and power efficiency.
Compared with the previous LPDDR5X, the product improves data processing speed by 33 percent by expanding bandwidth to increase the amount of data transferred per unit time. Its operating speed is at least 10.7 gigabits per second, exceeding the maximum speed of the previous generation.
Power consumption was reduced by more than 20 percent compared with the previous generation by adopting a sub-channel architecture as well as dynamic voltage and frequency scaling (DVFS) technology.
DVFS is a power management technology that optimizes power consumption and performance by adjusting voltage and frequency depending on the chip’s operating conditions.
Through this, the chip is designed to operate only the data paths required for a certain task and adjust frequency and voltage depending on the mobile environment. In high-performance situations such as gaming, DVFS is increased to enable maximum bandwidth operation, while during normal use the frequency and voltage are lowered to reduce power consumption.
SK hynix said LPDDR6 will enable longer battery life and an optimized multitasking experience, adding that it will prepare manufacturing depending on global mobile clients.
