"Global semiconductor sales increased sharply year-to-year in September, and year-to-date sales through September are more than 20 percent higher than at the same point last year," said John Neuffer, SIA CEO, in a statement. "Standouts among semiconductor product categories included memory products like DRAM and NAND flash, both of which posted major year-to-year growth in September, as well as logic products, which enjoyed double-digit growth year-to-year," said Neuffer.
Monthly data is given by the SIA and the ESIA as a three-month average, with the exception of year-to-date figures, 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.
