By constantly ramping up its current 18nm DRAM yield, Samsung has been able to hold an unchallenged position in the global DRAM market. According to market researcher IHS, the firm had a 46.6 share in the second quarter of this year, which is mainly due to its main competitors not yet manufacturing 18nm chips. They're on track to start in Q2 of 2017.
It's a mystery how Samsung has been able to refine its DRAM process in such a short period of time. Chung Eun-seung, executive vice president of Samsung’s DS division, suggested early last year that the company would mass produce 10-nm class chip technology by 2020. However, if it maintains its current pace, it can expect to start by early 2019.
