Flash partners Kioxia and Western Digital revealed this week a brand new generation of 3D NAND flash memory that promises to be much faster and far denser than anything they have produced before.

BiCS6 features 162 layers and 70% more bits per wafer than the preceding BiCS5 from a few years ago. That 70% allows for a 40% reduction in NAND chip size, helping to cut manufacturing costs.
