Macronix International Co (旺宏電子) saw its shares soar by almost 7 percent after the memorychip maker was selected to report its latest findings in making new memory chips at the prestigious International Electron Devices Meeting (IEDM).
One of the five reports is set to be about a new technology developed by Macronix to make flash memory chips that have a lifetime 100,000 times longer than usual, the Hsinchu-based chipmaker said in a statement.
Marconix, which supplies memory chips to video game console maker Nintendo Co, said it hoped to ramp up production of the so-called “self-healing” flash memory, aiming to make the technology another revenue source by licensing it and charging for its use.
Shares of Macronix jumped 6.92 percent to NT$8.96 yesterday.
Flash memory lifetimes are limited by use because repeated save and erase cycles degrade the funnel oxide that insulates flash memory cells. However, Macronix researchers have built flash memories that can heal themselves by means of tiny onboard heaters that provide thermal annealing to the spots where it is needed.
The devices have demonstrated record-setting endurance by withstanding more than 100 million save-erase cycles without losing data, compared with existing flash memory chips’ 1,000-cycle limit.
Macronix is scheduled to present five reports during the IEDM, which is to be held from Dec. 10 to Dec. 12 in San Francisco, California. It has presented 45 reports at these meetings over the past 12 years.
SETTING AN EXAMPLE: The commission suspended the bank’s two top executives as ‘a warning to all banks,’ while the fine is the biggest to be given to a bank in a single case The Financial Supervisory Commission (FSC) yesterday fined E.Sun Commercial Bank (玉山銀行) NT$20 million (US$693,698) over a theft scandal and punished the bank’s two top executives. A customer relationship manager surnamed Pan (潘) at the bank’s branch in Kaohsiung’s Fengshan District (鳳山) stole NT$140 million from 41 clients over the past seven years, the commission said. Pan secretly transferred the stolen money to accounts belonging to her and her family members by using clients’ debit cards, passwords or documents that were stamped using the clients’ personal stamps between July 2013 and June this year, the commission said. The commission suspended Ben Chen (陳炳良), the
Contract chipmaker Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) is expected to remain the third-largest IC supplier this year, unchanged from last year, IC Insights said yesterday. IC designer MediaTek Inc (聯發科) is expected to become the 11th-largest, up from 16th last year, the semiconductor market research firm said. TSMC is expected to post US$45.42 billion in sales, up 31 percent from last year, IC Insights said in a report released on its Web site. TSMC’s sales growth is largely due to a surge in orders from Apple Inc and HiSilicon Technologies Co (海思半導體) — two of its major clients — which
HARD ASK: At a meeting held by the MOEA to talk about the RCEP trade deal, trade associations said that they expect the government to push for more free-trade deals Business representatives yesterday urged the government to slow the appreciation of the New Taiwan dollar, saying that some Taiwanese industries have been undercut by rivals due to unfavorable foreign exchange rates. The government should also assist local industries to expand their domestic market, and push for more bilateral trade deals so that Taiwanese companies can enjoy zero or preferential tariffs on exports, following the nation’s exclusion from the Regional Comprehensive Economic Partnership (RCEP) which was signed by 15 Asia-Pacific nations on Nov. 15, they said at a meeting with the Ministry of Economic Affairs (MOEA). Some participants said that the NT dollar’s
BREATH OF LIFE: The firm said the under-utilized plant should start mass production in the first quarter, timed to coincide with Intel Corp’s release of its Ice Lake server chip Hon Hai Precision Industry Co (鴻海精密) plans to assemble key components for Google servers at its plant in Wisconsin, people familiar with the matter said, finally breathing life into a factory that US President Donald Trump hailed as crucial to bringing manufacturing back to the US. The company has decided to locate production for this new contract at the existing complex rather than make the components at home or in China, the people said, asking not to be identified. The under-utilized plant should start mass production in the first quarter, timed with the release of Intel Corp’s Ice Lake server chips,
