Samsung Electronics Co., the world\'s top memory chip maker, maintained its share of the global chip market at more than 10 percent in the first quarter on the back of a growth in system semiconductors, industry data showed Monday. According to the data compiled by market information provider iSupply, Samsung accounted for 10.5 percent or US$7.77 billion of the global semiconductor market in the January-March period to rank second among the world\'s major chip makers.  Intel Corp. of the U.S. took the top spot with $11.16 billion in sales for a 15.1 percent share, the data showed. Samsung held on to the top position in the memory chip market in the first quarter with a 33.3 percent share and $4.71 billion in sales, according to the data.  Last year, Samsung accounted for 10.3 percent or $31.26 billion of the global semiconductor market. It marked the first time that Samsung\'s global market share had topped the 10 percent mark.  In 2011, Samsung secured a 9.2 percent market share with sales of $28.56 billion, the data showed.  The improvement in market share is attributable to its recent active investment in system semiconductors including application processors, according to experts.
