China probes dominant DRAM chip makers – Samsung Electronics, SK Hynix and Micron

China has launched an investigation into Samsung Electronics Co, SK Hynix and Micron Technology, the three semiconductor makers who control the market for DRAM memory chips.

A source with knowledge of the matter said Beijing was probing price-fixing allegations as DRAM prices had risen sharply, the first such investigation by China.

“The investigation has kicked off in earnest,” the source said, requesting anonymity due to the sensitivity of the matter.

Prices for DRAM chips, which help devices perform multiple tasks, have more than doubled in two years as servers, gaming PCs and cryptocurrency mining devices demand more firepower to process large amounts of streaming data. Although China is investing heavily to build up its still nascent chip industry, it is currently the largest importer of memory products, consuming 20 per cent of the world’s DRAM, according to research firm Trendforce.

All three companies said officials from China’s State Administration for Market Regulation had visited their offices recently.

“China (is) trying to protect their PC and smartphone market from rising DRAM costs. Typically, China PC and smartphones sell at lower costs/margins than those in other countries,” said Stifel Nicolaus analyst Kevin Cassidy.

A Samsung spokesman said the company was cooperating with the Chinese authorities, but did not provide more details on the visit. A SK Hynix spokesman also declined to give further details.

The crackdown on chip makers was to ensure fair competition, said the Global Times, a state-backed Chinese tabloid run by the ruling Communist Party’s official People’s Daily. A potential probe was first flagged late last year when Chinese state media reported that regulators approached South Korea’s Samsung over rising prices.

The DRAM sector has been a frequent target of regulatory probes globally over price-fixing allegations as the industry has seen a flurry of deals that left the two South Korean firms and their US rival now commanding 96 per cent of the market.

Samsung had 44.9 per cent market share in the first quarter, while SK Hynix has 27.9 per cent and Micron has 22.6 per cent, according to Trendforce. In April, they were slapped with a class-action lawsuit brought on behalf of U.S consumers over allegations that they conspired to inflate DRAM prices.

Chinese firms have had a number of overseas deals to buy foreign chip companies blocked by US regulators in recent years, including a bid by Tsinghua Unigroup to acquire Micron Technology.
