SEOUL, July 8 (Reuters) - Samsung Electronics ( SSNLF )

on Tuesday projected a 56% drop in second-quarter

operating profit from a year earlier, missing analysts'

estimates.

Its chip business struggled with weak sales of artificial

intelligence chips, dogged by delays in the supply of its latest

chips to Nvidia ( NVDA ) and continued losses in its contract

chip manufacturing business, analysts said.

The world's largest memory chipmaker estimated an operating

profit of 4.6 trillion won for the April-June period, versus a

6.2 trillion won LSEG SmartEstimate.
