Worldwide semiconductor revenue is forecast to total $451 billion in 2018, an increase of 7.5 percent from $419 billion in 2017, according to Gartner, Inc. This represents a near doubling of Gartner's previous estimate of 4 percent growth for 2018.

"Favorable market conditions for memory sectors that gained momentum in the second half of 2016 prevailed through 2017 and look set to continue in 2018, providing a significant boost to semiconductor revenue," said Ben Lee, principal research analyst at Gartner. "Gartner has increased the outlook for 2018 by $23.6 billion compared with the previous forecast, of which the memory market accounts for $19.5 billion. Price increases for both DRAM and NAND flash memory are raising the outlook for the overall semiconductor market."
