Adds revenue and full earnings later this month, paragraphs 3-4

SEOUL, July 7 (Reuters) - Samsung Electronics 005930.KS on Tuesday forecast a 19-fold jump in second-quarter operating profit from a year earlier, as AI-driven demand continued to lift memory chip prices.

The world's largest memory chipmaker estimated April-June operating profit at 89.4 trillion won ($58.44 billion), beating an LSEG SmartEstimate of 87.3 trillion won, according to a regulatory filing, and up from 4.7 trillion won a year earlier.

Revenue would likely rise 129% to 171 trillion won from a year earlier, it said.

Samsung is expected to release detailed results, including a breakdown of earnings of each of its business divisions, later this month.
