Samsung’s ‘extreme ultraviolet’ RAM is set to be super-fast – but when’s it coming to PCs?


Samsung has announced that it has started mass producing what it claims is the ‘industry’s smallest’ 14-nanometer (nm) DDR5 DRAM, offering drastically improved speeds over the previous generation DDR4 RAM (which is what most of our PCs are currently using).

By utilising the pretty awesome sounding extreme ultraviolet (EUV) technology, Samsung has increased the number of EUV layers in its DDR5 chips, allowing them to be smaller, but with a higher density.

This looks set to bring a range of exciting possibilities. For a start, Samsung says its 14nm DDR5 DRAM will be able to hit speeds of 7.2 gigabits per second (Gbps), which is over twice the speed of DDR4, which peaks at 3.2Gbps.

By being smaller and denser ...
