Macronix International Co (旺宏) was yesterday the most active stock on the Taiwan Stock Exchange, after the memorychip maker said it has secured a significant order for its new 19-nanometer single-level cell (SLC) NAND flash memory chips used in set-top boxes.
Some 88.59 million Macronix shares were traded yesterday, a sharp rise from 55.06 million on Thursday, data compiled by the Taiwan Stock Exchange showed.
Macronix’s share price has climbed 14.34 percent to NT$31.50 over the past month, outpacing the TAIEX’s rise of 1.99 percent.
“We began shipping the product to a US customer a few days ago, as the Christmas holiday season is just around the corner. The 19-nanometer SLC NAND is used in set-top boxes,” Macronix chairman Miin Wu (吳敏求) told reporters on Thursday.
“It was our first 19-nanometer SLC NAND order,” he added.
Customers tend to opt for 4-gigabyte SLC NAND flash memory chips to cope with the increasingly complex systems installed in set-top boxes, which require more memory, Wu said.
With more providers offering ultra-high-definition 4K or 8K content, Macronix expects consumer electronics devices to be equipped with more memory, he said.
Macronix has budgeted NT$14 billion (US$451 million) in capital spending this year for technological upgrades, including converting NAND flash memory chip production from 36-nanometer process to 19-nanometer.
Apart from that, Macronix expects to complete development of its first 3D NAND flash memory chip in 2021, Wu said.
The prices of NAND flash, NOR flash memory chips and ROM chips have stabilized this quarter, he said, but it is unclear whether prices would pick up any time soon.
Macronix mainly supplies ROM chips to Japan’s Nintendo Co.
Chip prices have been on a downward spiral since the third quarter of last year amid sluggish demand, partly due to a trade dispute between the US and China, the memorychip maker said.
Asked whether an improved pricing environment would help Macronix’s revenue grow 30 percent sequentially this quarter as some analysts have forecast, Wu declined to comment.
The third quarter is usually peak season for Macronix, with shipments increasing from the previous quarter, he said.
Seasonal demand has helped boost the utilization of its 12-inch fab to almost 100 percent, Wu said.
DECOUPLING? In a sign of deeper US-China technology decoupling, Apple has held initial talks about using Baidu’s generative AI technology in its iPhones, the Wall Street Journal said China has introduced guidelines to phase out US microprocessors from Intel Corp and Advanced Micro Devices Inc (AMD) from government PCs and servers, the Financial Times reported yesterday. The procurement guidance also seeks to sideline Microsoft Corp’s Windows operating system and foreign-made database software in favor of domestic options, the report said. Chinese officials have begun following the guidelines, which were unveiled in December last year, the report said. They order government agencies above the township level to include criteria requiring “safe and reliable” processors and operating systems when making purchases, the newspaper said. The US has been aiming to boost domestic semiconductor
Nvidia Corp earned its US$2.2 trillion market cap by producing artificial intelligence (AI) chips that have become the lifeblood powering the new era of generative AI developers from start-ups to Microsoft Corp, OpenAI and Google parent Alphabet Inc. Almost as important to its hardware is the company’s nearly 20 years’ worth of computer code, which helps make competition with the company nearly impossible. More than 4 million global developers rely on Nvidia’s CUDA software platform to build AI and other apps. Now a coalition of tech companies that includes Qualcomm Inc, Google and Intel Corp plans to loosen Nvidia’s chokehold by going
ENERGY IMPACT: The electricity rate hike is expected to add about NT$4 billion to TSMC’s electricity bill a year and cut its annual earnings per share by about NT$0.154 Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) has left its long-term gross margin target unchanged despite the government deciding on Friday to raise electricity rates. One of the heaviest power consuming manufacturers in Taiwan, TSMC said it always respects the government’s energy policy and would continue to operate its fabs by making efforts in energy conservation. The chipmaker said it has left a long-term goal of more than 53 percent in gross margin unchanged. The Ministry of Economic Affairs concluded a power rate evaluation meeting on Friday, announcing electricity tariffs would go up by 11 percent on average to about NT$3.4518 per kilowatt-hour (kWh)
OPENING ADDRESS: The CEO is to give a speech on the future of high-performance computing and artificial intelligence at the trade show’s opening on June 3, TAITRA said Advanced Micro Devices Inc (AMD) chairperson and chief executive officer Lisa Su (蘇姿丰) is to deliver the opening keynote speech at Computex Taipei this year, the event’s organizer said in a statement yesterday. Su is to give a speech on the future of high-performance computing (HPC) in the artificial intelligence (AI) era to open Computex, one of the world’s largest computer and technology trade events, at 9:30am on June 3, the Taiwan External Trade Development Council (TAITRA) said. Su is to explore how AMD and the company’s strategic technology partners are pushing the limits of AI and HPC, from data centers to
