The DRAM and NAND flash markets continue to closely follow the original IC industry cycle model whereby the market cycles are primarily driven by fluctuations in capital spending and capacity. Including IC Insights’ forecast for 2019, it appears that little has changed regarding the extremely volatile nature of DRAM market cycles.

At $99.4 billion, the DRAM market was by far the largest single product category in the semiconductor industry in 2018, exceeding NAND flash ($59.4 billion), the second-largest market by $40.0 billion. Since 2013, the memory market has been a tailwind (i.e., positive influence) on total annual worldwide IC market growth and only once a headwind (i.e., negative influence).

A memory market segment surge of 64% in 2017 helped boost the total IC market growth rate by a whopping 14 percentage points. Despite a fourth quarter slowdown, the 2018 memory market grew by a strong 26%, providing a very substantial six point positive impact on worldwide IC market growth for the full-year.

For 2019, the memory market is forecast to be a significant headwind on worldwide IC market growth. The total memory market is forecast to fall by 24% this year (a decline of $38.6 billion). The big decline in the memory market is forecast to drag down total IC market growth by 9%. Factoring out memory, the total IC market growth rate is forecast to be flat (0%) this year.
