Inotera Memories Incfs (‰Ø˜±‰È‹Z) fast migration to advanced 20-nanometer (nm) DRAM technology is the driving force behind Micron Technology Incfs plan to continue its buyout of the memorychip maker, TrendForce Corp (W–M‰È‹Z) said.

The Taipei-based researcher said the NT$130 billion (US$4.01 billion) acquisition would create a win-win situation for Micron and Nanya Technology Corp (“옱‰È‹Z), which agreed to sell a 24 percent stake in Inotera to the US memorychip maker.

The deal is crucial for Nanya, as the share sale would give it access to next-generation technologies from Micron, extending their partnership on 20nm technology, TrendForce said in a report released on Monday after Inotera told a media briefing that Micron is to acquire the remaining 67 percent stake from Nanya and other members of Formosa Plastics Group (‘ä‘YWš£).

Micron is the worldfs second-largest DRAM supplier, with an 18.5 percent global market share by revenue last quarter, behind South Koreafs Samsung Electronics Cofs 46.4 percent and SK Hynix Incfs 27.1 percent, according to TrendForce data.

For Micron, gInotera has replaced Micron Memory Japan (MMJ) as the most important [20nm chip] manufacturing site for the company,h TrendForce said.

MMJ was previously named Elpida Memory Inc before being acquired by Micron in 2013.

gInotera was the first company to start the migration to 20nm technology,h among members of the Micron camp, including MMJ, Micron Memory Taiwan, Inotera and Micronfs US plants, TrendForce said.

In September, Inotera is to start shipping 20nm chips to customers, the researcher said.

Taoyuan-based Inotera earlier this year said that it is on track to migrate all of its capacities to 20nm chips by the end of this quarter.

As Micronfs output growth next year is to come primarily from the migration to 20nm chips, gInotera will play an irreplaceable role in the Micron camp,h TrendForce said.

Inotera contributes 100,000 12-inch wafers a month to Micron, making up about 30 percent of the US memorychip makerfs total monthly DRAM capacities of 315,000 12-inch wafers, the researcher said.

Micronfs decision on Wednesday last week to postpone the acquisition sent Inotera shares down 10 percent yesterday to end at NT$23.85 in Taipei trading, after plunging 9.86 percent on Monday, erasing more than NT$36.57 billion in market cap in just two days.

Inotera was yesterday fined NT$300,000 by Taiwan Stock Exchange Corp for the belated disclosure of Micronfs delayed closing of the acquisition deal.

gInotera has violated rules of disclosing important corporate information,h the Taiwan Stock Exchange said in a statement.

gThe violation has caused a significant impact on its stock price,h it added.

Inotera should have applied to suspend trading of its shares on Tuesday last week, one day before Micron made the announcement, as related rules stipulate, the statement said.
