South Korea's memory chip giants were the only two companies to post revenue growth in 2009, Gartner said, after the memory chip industry rebounded. Everyone else showed declines. Samsung Electronics, the world's largest memory chip maker, maintained its second place rank globally with $17.7 billion in revenue, up from $17.4 billion a year earlier. The company took a 7.7 percent share of the global chip market and its revenue was a little over half of Intel's, which was $33.3 billion last year.

Intel stays atop chip market but Samsung gains in tough 2009
