Samsung says talk of defective chips "groundless"

SEOUL, June 19 (Reuters) - Samsung Electronics Co Ltd (005930.KS), the world's largest maker of memory chips, said on Thursday a Taiwanese newspaper report that some of its chips had problems was "groundless."

Market talk about defective dynamic random access memory (DRAM) chips sent Samsung shares down 3.27 percent to 681,000 won by 0153 GMT, compared with the wider market's 1.58 percent loss. (Reporting by Lee Chang-ho, writing by Rhee So-eui; editing by Jonathan Hopfner)
