DRAM and NAND flash are expected to be the two semiconductor products that outshine this year, a report showed Saturday, boding well for South Korean chipmakers that dominate the world's memory chip market.

Sales growth for DRAM and NAND flash were projected to be 18 percent and 17 percent, respectively, making them the two sharpest-growing chips among the 33 integrated circuit products in 2021, according to the McClean Report released by market tracker IC Insights.

DRAM, or dynamic random-access memory, is a volatile semiconductor memory that retains data as long as power is supplied. It is commonly used in personal computers, workstations and servers.

"Laying claim as the fastest growing IC product segment is familiar territory for the DRAM market," IC Insights said. "DRAM was also ranked as the fastest-growing IC segment in 2013, 2014, 2017, and 2018."

NAND flash is a type of non-volatile storage that does not require power to store data.

"The transition to 5G technology within many of these same computing applications and smartphones is forecast to boost NAND revenue growth 17 percent in 2021," it said.

Both DRAM and NAND flash are the main products for South Korea's two largest chipmakers -- Samsung Electronics and SK hynix.

As of the third quarter of 2020, Samsung dominated the global DRAM market with a 41.3 percent share, with SK hynix coming in second with a 28.2 percent share, according to market researcher TrendForce.

In the NAND flash market, Samsung held a 33.1 percent share in the third quarter, while SK hynix had an 11.4 percent share.

IC Insights' outlook is in line with the two companies' 2021 forecast of their memory business announced earlier this week.

Samsung said its memory business, specifically the DRAM market, is expected to see a recovery during the first half of the year thanks to strong demand from mobile and server applications, although geopolitical and economic uncertainties remain.

SK hynix projected the DRAM demand growth this year to be around the high 10 percent and 20 percentage range and that of NAND flash to be in the low 30 percent range.

Meanwhile, IC Insights said only five IC product segments were projected to outpace the entire IC market growth in 2021.

In addition to DRAM and NAND flash, two automotive IC products, application-specific analog and special purpose logic chips, as well as embedded microprocessors were expected to grow faster that the total IC market's growth of 12 percent. (Yonhap)
