Total worldwide semiconductor revenues reached US$315 billion in 2013, up 5% from 2012, according to Gartner. The combined revenues of the top 25 semiconductor vendors increased 6.9% during 2013. This was a better performance than the rest of the market, whose revenue growth was 0.9%, and was due, in part, to the concentration of memory vendors in the top ranking. The memory market increased 23.5% in 2013, the firm said.

　　"After a weak start to 2013 due to excess inventory, revenue growth strengthened during the second and third quarters before leveling off during the fourth quarter," said Andrew Norwood, research VP at Gartner. "Memory, and in particular DRAM, led this growth; not due to strong demand, but rather weak supply growth that pushed pricing higher. In fact, the overall market faced a number of demand headwinds during the year, with PC production declining 9.9% and the premium smartphone market showing signs of saturation as growth tilted toward lower-priced, albeit quite capable, entry-level and mid-range smartphone models."

　　Intel saw a second year of revenue contraction with sales down 1%, mostly due to falling PC sales. However, it continues to command a clear lead, holding the number one position for the 22nd consecutive year with 15.4% of the market.

　　Samsung Electronics maintained the number two position for the 12th year. The company has almost doubled its share of the market since 2002. Samsung's memory business saw strong revenue growth for both DRAM and NAND flash.

　　In third position, Qualcomm's semiconductor business grew 30.6%. This was achieved due to its market-leading position in smartphone application processors and Long Term Evolution (LTE) baseband processors. The company continues to outperform the market, with its mobile station modem unit shipments increasing 21% during 2013, the firm said.

　　At number four, SK Hynix's revenues increased 40.8%, representing the strongest organic growth in the top 25 and pushing the company into the top five for the first time. Micron Technology saw the biggest revenue growth among the top 25 due to its acquisition of Elpida Memory, which Gartner counts under Micron from third-quarter 2013 onward, the firm added.
