SEOUL, April 25 (Reuters) - South Korea's SK Hynix Inc said on Tuesday its first-quarter operating profit rose 339 percent from a year earlier, beating market expectations and setting a record due to strong demand for memory chips.
The world's second-biggest memory chip maker behind Samsung Electronics Co Ltd said its January-March profit was 2.5 trillion won ($2.20 billion). That compared with a 2.4 trillion won Thomson Reuters StarMine SmartEstimate from a survey of 24 analysts.
