Samsung is fond of bragging about its progress on memory chips, but this is one time where it made a particularly notable breakthrough. The Korean firm has started mass production of 16-gigabit LPDDR5 mobile RAM chips that are billed as the first memory ever to be made using extreme ultraviolet lithography, which uses lasers and light-sensitive chemicals to etch silicon. Aside from giving Samsung an edge over rivals, it reportedly clears a “major developmental hurdle” in scaling RAM — this could offer much more room for the industry to grow.

This also translates to some immediate real-world gains, as you might expect. The 6.4Gbps of bandwidth is about 16 percent faster than the 12-gigabit chips seen before, while a 16GB package of chips is about 30 percent thinner. That could lead to slimmer phones or space for components like batteries and cameras.
