Samsung has started mass production of 16 gigabit LPDDR5 RAM chips (equivalent to 2GB each). Samsung said this is the first RAM chip produced by 10nm ultraviolet printing technology (EUV), which means it will use ultraviolet rays and light-sensitive chemicals to engrave transistors on a plate. silicon. There is a high chance that the new smartphones from Samsung and many other brands around the world will use the aforementioned 16 gigabit LPDDR5 RAM chip by 2021.
The benefit of this “1z” line is that it produces smaller transistors (or a higher density of transistors per unit area), which is more energy efficient. A 16GB RAM package only needs 8 chips, previously when Samsung operated the “1y” line (previous generation) it took 12 chips to achieve the same capacity (ie more power, more area consuming).
Previously, EUV technology was used by TSMC to manufacture processor chips, and Exynos 9850, Exynos 990 were also made of EUV lines.
Samsung added that its 16Gb RAM chip has a data transfer rate of 6400Mbps, 16% faster than the 12Gb (5500Mbps) RAM line many smartphones are using. When packed into a 16GB RAM set, the LPDDR5 chip can transfer 10 5GB Full-HD movies, or 51.2GB of data, in just 1 second.
Also on this occasion, Samsung said that the plant is used to produce LPDDR5 16 gigabit RAM chips which is currently the largest semiconductor production line in the world. The factory, named Pyeongtaek Line 2, measures 128,900 square meters (about 16 soccer fields) and is located in Korea.
