According to IC Insights, DRAM and NAND flash are expected to be the two fastest-growing product segments in 2021 with 18% and 17% sales growth, respectively.
Laying claim as the fastest growing IC product segment is familiar territory for the DRAM market. DRAM was also ranked as the fastest-growing IC segment in 2013, 2014, 2017, and 2018.
On the other hand, due to its extreme cyclicality, DRAM has also been among the poorest performing categories. Collapsing prices resulted in the DRAM market falling -37% in 2019, which ranked it last among the 33 IC product categories that year. (Laoyaoba, IC Insights)
