South Korean tech giant Samsung Electronics Co. posted a solid gain in sales of semiconductors for the second quarter of the year, narrowing its revenue gap with its bigger rival Intel Corp., according to industry data Tuesday.

Samsung's semiconductor sales rose 11 percent on quarter to $10.3 billion for the second quarter, while Intel's sales fell 1 percent to $12.9 billion for the same quarter, the data compiled by IC Insights showed.

In the first quarter, Intel reported $13.1 billion in sales of semiconductors and Samsung posted $9.3 billion, according to the data.

Hit by slumping prices of DRAM chips, widely used in personal computers, Samsung's semiconductor sales had been on a decline.

However, a rebound came in the second quarter, thanks to strong sales of NAND memory chips for smartphones and other portable devices Samsung has been also narrowing an annual market-share gap with Intel.

The market-share gap between Samsung and Intel stood at 5.3 percentage points in 2012, 4.2 percentage points in 2013, 3.4 percentage points in 2014 and 3.2 percentage points in 2015.

Meanwhile, SK hynix Inc. was ranked sixth, with its sales of semiconductors at $6.4 billion for the first half of the year, the data showed. (Yonhap)
