Memory was the largest semiconductor category by sales with $158.0 billion in 2018, and the fastest growing, with sales increasing 27.4 percent. Within the memory category, sales of DRAM products increased 36.4 percent and sales of NAND flash products increased 14.8 percent.
Logic ($109.3 billion) and microprocessor and microcontroller ICs ($67.2 billion) were the next most significant categories. Other fast-growing product categories in 2018 included power transistors (14.4 percent growth/total sales of $14.4 billion) and analog products (10.8 percent growth/total sales of $58.8 billion).
Annual sales increased substantially across all regions: China (20.5 percent), the Americas (16.4 percent), Europe (12.1 percent), Japan (9.2 percent), and Asia Pacific/All Other (6.1 percent). For the month of December 2018, year-to-year sales increased in China (5.8 percent), Europe (2.8 percent), and Japan (2.3 percent), but fell in Asia Pacific/All Other (-0.7 percent) and the Americas (-6.2 percent).
Monthly data is given by the SIA and other bodies as a three-month average although the WSTS organization tracks actual monthly data. The SIA and other regional semiconductor industry bodies opt to use averaged data because it evens out the actual data that typically shows troughs at the beginnings of quarters and peaks at the ends of quarters.
