SEOUL, April 30 (Reuters) - Samsung Electronics reported on Tuesday a more than 10-fold rise in its first-quarter operating profit, as memory chip prices rose steeply from a severe downturn thanks in part to a boom in artificial intelligence.

The world's biggest maker of memory chips and TVs said operating profit rose to 6.6 trillion won ($4.8 billion) in January-March, up from 640 billion won a year earlier.

That was in line with Samsung's own estimate of 6.6 trillion won flagged earlier this month. ($1 = 1,374.1900 won) (Reporting by Joyce Lee and Heekyong Yang; Editing by Jamie Freed)
