Japan’s Toshiba Corp is teaming up with US chip giant SanDisk Corp to produce a “3D” memory chip they hope will allow users to save up to 50 hours of ultra-high-definition video.
In a deal worth a reported ￥500 billion (US$4.84 billion) the companies are to build a factory to make flash memory consisting of several layers of semiconductors stacked together to give as much as a terabyte — 1,000 gigabytes — of storage.
That is about 16 times bigger than the largest 64-gigabyte Toshiba memory currently available in smartphones and tablet devices.
Toshiba will demolish its existing plant in Japan to build a new facility that will house production apparatus using technologies from both firms and which the firms hope will start operating in 2016, a statement said.
“In about five years [from the planned start of the factory], we would like to produce one-terabyte products,” a Toshiba spokeswoman said.
The plan comes at a time of increasing competition among the world’s technology firms to meet demand for ever-higher capacity memory chips for consumers increasingly using mobile devices such as smart phones, tablet computers and wearable gadgets.
The spread of high-definition video, with so-called 4K-resolution screens at the leading edge, is boosting demand for computing memory to store content.
“Small, high-capacity memories can of course be applied to smartphones, but they could also be used for wearable devices,” the Toshiba spokeswoman said.
Manufacturers have traditionally competed with regular chips by trying to make the physical object smaller.
Toshiba, along with major rivals such as Samsung, believe they are reaching the physical limit, and are shifting toward 3D memories, where layering — effectively a third dimension — is used to boost the capacity of objects the same size.
“Our determination to develop advanced technologies underlines our commitment to respond to continued demand [for] flash memory,” Toshiba senior vice president Yasuo Naruke said in a statement
SanDisk president and chief executive Sanjay Mehrotra said the plant “will advance our leadership in memory technology into the 3D ... era.”

TECH RACE: The Chinese firm showed off its new Mate XT hours after the latest iPhone launch, but its price tag and limited supply could be drawbacks China’s Huawei Technologies Co (華為) yesterday unveiled the world’s first tri-foldable phone, as it seeks to expand its lead in the world’s biggest smartphone market and steal the spotlight from Apple Inc hours after it debuted a new iPhone. The Chinese tech giant showed off its new Mate XT, which users can fold three ways like an accordion screen door, during a launch ceremony in Shenzhen. The Mate XT comes in red and black and has a 10.2-inch display screen. At 3.6mm thick, it is the world’s slimmest foldable smartphone, Huawei said. The company’s Web site showed that it has garnered more than
PARTNERSHIPS: TSMC said it has been working with multiple memorychip makers for more than two years to provide a full spectrum of solutions to address AI demand Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday said it has been collaborating with multiple memorychip makers in high-bandwidth memory (HBM) used in artificial intelligence (AI) applications for more than two years, refuting South Korean media report's about an unprecedented partnership with Samsung Electronics Co. As Samsung is competing with TSMC for a bigger foundry business, any cooperation between the two technology heavyweights would catch the eyes of investors and experts in the semiconductor industry. “We have been working with memory partners, including Micron, Samsung Memory and SK Hynix, on HBM solutions for more than two years, aiming to advance 3D integrated circuit
Vanguard International Semiconductor Corp (世界先進) and Episil Technologies Inc (漢磊) yesterday announced plans to jointly build an 8-inch fab to produce silicon carbide (SiC) chips through an equity acquisition deal. SiC chips offer higher efficiency and lower energy loss than pure silicon chips, and they are able to operate at higher temperatures. They have become crucial to the development of electric vehicles, artificial intelligence data centers, green energy storage and industrial devices. Vanguard, a contract chipmaker focused on making power management chips and driver ICs for displays, is to acquire a 13 percent stake in Episil for NT$2.48 billion (US$77.1 million).
