"Samsung Electronics has already started the mass production of 18-nm DRAM chips early this year and is preparing for the production of 15-nm and 16-nm DRAM in the second half of the next year."

This has been confirmed apparently by Samsung's 1Y announcement a few days ago.

Features:
- 30% more chips per wafer compared to 18 nm (i.e, 15-16 nm)
- air spacer to reduce capacitance
- circuit design for energy efficiency with improved performance
- high-sensitivity data sensing
- uses existing lithography (i.e., no EUV)
