Worldwide semiconductor revenue is projected to total $311 billion in 2013, a 4.5 percent increase from 2012 revenue, according to Gartner, Inc.

Due to economic headwinds and an inventory correction, the fourth quarter projections have been revised down from the previous quarter's forecast of $330 billion, said Gartner in a release.

Analysts have also reduced growth predictions for 2012 with semiconductor revenue expected to total $298 billion, down 3 percent from 2011. Gartner's third quarter forecast had put revenue at $309 billion for 2012, which would have meant an increase of 0.6 percent from 2011.

"The looming fiscal cliff, ongoing European debt crisis, slower emerging market growth and regional tensions have all played a part in reduced growth projections for semiconductor revenue in both 2012 and 2013," said Peter Middleton, principal analyst at Gartner.

"Inventory levels were already high at the start of the second half of 2012, and as PC demand rolled off, supply simply overshot demand."

The report further added that the semiconductor market was further depressed when DRAM prices failed to rebound in 2012.

Gartner predicts that the DRAM market will not recover until the second half of 2013, when lower supply growth is expected to pull the market into a period of undersupply.

This should prove a turning point for the semiconductor industry; memory is expected to lead the recovery with 15.3 percent growth and total semiconductor revenue is projected to reach $342 billion in 2014, an increase of 9.9 percent from 2013, says Gartner.

The "Apple effect" is expected to remain pronounced in 2013, helping drive strong NAND and application-specific integrated circuit (ASIC) revenue growth of 17.2 percent and 9.4 percent, respectively.

Gartner counts the A4, A5 and A6 application processors from Apple as ASICs, because these are custom processors, designed and solely used by Apple. ASICs will also benefit from the new generation of video game consoles being introduced in late 2012 and 2013.
