Samsung has begun mass production of the first 16Gb LPDDR5 RAM chips. These are the largest chips made so far by the South Korean giant, which says it will use them in next-generation top-of-the-range 5G smartphones. RAM modules are made from multiple chips put together: a 16-inch chip Gb (gigabit) has a capacity of 2 GB (gigabyte). Samsung already produces 16 GB modules of LPDDR5 RAM, consisting of 8 12 Gb and 4 8 Gb chips.
The chips are built in the "Line 2" factory in Pyeongtaek, South Korea. Samsung calls it the largest semiconductor manufacturing plant in the world. The chips consist of third-generation 10nm V-NAND memories, for the first time mass-produced with EUV (Extreme Ultraviolet lithography, the same used for the latest mobile processors / SoCs). The result is that the new 16 gigabit chips are 30% thinner than the 12 gigabit ones. The chips guarantee higher transfer speeds, despite their small size: it reaches 6,400 megabits per second – equal to 51.2 GB per second.
A 16GB RAM module will therefore only require 8 16Gb chips: it will be a simpler and more compact structure. This is exactly the use that the company intends to make of them: we can therefore expect them in the next generation top-of-the-range smartphones. In the future, we could see them arrive in the automotive sector: Samsung has already started the additional reliability tests (mainly related to weather resistance and extreme climatic conditions).
