SEOUL, Nov 27 (Reuters) - Samsung Electronics ( SSNLF )

said on Wednesday it has named Jun Young-hyun as the

new head of its memory chip business and Co-CEO of the company,

while Han Jin-man will become the head of the foundry business

with a promotion as president.

Samsung also named Nam Seok-woo who has been head of chip

factory engineering and operations as the Chief Technology

Officer of the foundry business in a newly created role.

The major reshuffle of its top rank comes as shares of the

tech giant have steadily fallen since August on investor

concerns that it keeps lagging its rivals in supplying high-end

chips to Nvidia ( NVDA ) in the booming AI market.
