SEOUL, July 31 (Reuters) - Samsung Electronics ( SSNLF )

forecasted robust artificial intelligence-driven

demand for chips in the second half of this year, as it reported

a more than 15-fold rise in its second-quarter operating profit.

"In the second half of 2024, AI servers are expected to take

up a larger portion of the (memory) market as major cloud

service providers and enterprises expand their AI investments,"

Samsung said in a statement.

Rebounding semiconductor prices stoked by the AI boom lifted

June quarter earnings for the world's biggest maker of memory

chips, smartphones and TVs from a low base a year ago.

Samsung's share price rose 0.9% in morning trade versus a

0.5% rise in the benchmark index.

Operating profit rose to 10.4 trillion won ($7.52 billion)

in April-June, up from 670 billion won a year earlier, Samsung

said.

It was Samsung's highest operating profit since the third

quarter of 2022, spurred by the chip division returning to form

as the tech giant's cash cow after a slump caused by weak

post-pandemic demand for gadgets that use the chips.

CHIPS BOOM

The chip division reported a 6.45 trillion won profit, its

highest since the second quarter of 2022, and its second

consecutive quarterly profit.

Explosive demand for high-end DRAM chips such as high

bandwidth memory (HBM) chips used in AI chipsets, as well as

chips used in data centre servers and gadgets that run AI

services have helped to lift chip prices.

South Korean rival SK Hynix ( HXSCF ) also said last

week demand for AI chips will continue to get stronger, as it

posted its highest quarterly profit since 2018.

Samsung has yet to meet AI chip leader Nvidia's ( NVDA )

standards for fifth-generation HBM chips called HBM3E, though

Samsung's fourth-generation HBM - dubbed HBM3 - has been cleared

by Nvidia ( NVDA ) for use in its less-sophisticated graphics processor

called the H20, developed for the Chinese market, sources have

told Reuters.

With production capacity being concentrated on HBM, server

DRAMs and server solid-state drives (SSDs) for AI applications,

conventional supply of PC and mobile memory chips will be

constrained in the second half of the year, Samsung said.

Revenue rose 23% to 74 trillion won.
