Seoul, Mar 29 (IANS): Samsung Electronics and SK hynix, the world's two largest memory chip makers, are forecast to report robust earnings in the first quarter, despite a hike in raw material prices and continued global supply woes, a financial data firm said Tuesday.

Samsung is estimated to log 13.89 trillion won ($11.3 billion) in operating profits in the three months ending March 31, up 38.64 per cent from a year ago, while SK hynix is expected to top 3.1 trillion won, up 137.08 per cent, according to a survey by Yonhap Infomax, the financial data firm of Yonhap News Agency.

Samsung's first-quarter sales are forecast to come in at 75.2 trillion won, exceeding 70 trillion won for the third consecutive quarter.

It is up 15.02 per cent from a year earlier.SK hynix is expected to post 11.5 trillion won in quarterly sales, up 36.36 per cent from the same time last year and surpassing 10 trillion won for the first time.

The rosy forecasts both for Samsung and SK hynix came in spite of difficult external business conditions, ranging from volatile raw material costs spurred by Russia's invasion of Ukraine to the global supply chain disruption.

The two companies said there was no immediate impact from the war in Ukraine on their chip production thanks to "diversified sources for materials" and ample inventory of key materials. The two chipmakers, combined, take up more than 70 per cent of the global DRAM market.

The positive outlook is supported by a sooner-than-expected rebound in memory chip prices amid the continued shortage of semiconductors and strong demand for DRAM used in servers.

Market researcher TrendForce said prices of DRAM, a volatile memory chip used mostly in computers and servers, could fall up to 13 per cent in the first quarter and five percent in the second.

But they will rebound starting in the second half, thanks to "the rise in DDR5 penetration rate and the arrival of peak seasonal demand".

DDR5 is the next-generation of PC main memory with higher speed and bigger memory.

Supply disruptions of crucial raw materials used in the chipmaking process, such as neon, however, are stoking concerns about higher chip prices down the road.

According to TrendForce, Ukraine supplies nearly 70 per cent of the world's highly purified neon gas used to etch circuit designs into silicon wafers to produce semi-conductors.

Omdia, another market research firm, earlier noted the last time Russia invaded Ukraine in 2014, neon prices shot up 600 per cent, sending wide-reaching repercussions and causing havoc in the global chip industry.
