South Korea has developed ternary semiconductor binary outdated?
A research team in South Korea has successfully implemented a more energy-efficient ternary metal oxide semiconductor on large-size wafers. Kyung Rok Kim, a professor at the Department of Electronic and Computer Engineering at Ulsan University of Science and Technology, South Korea, and his team have successfully developed a semiconductor that operates on a ternary logic system rather than an existing binary logic system. The research paper was published in "Nature · Electronics".

The research team said that the use of a ternary system consisting of 0, 1, 2 reduces the amount of information that the semiconductor needs to process, improves the speed of information processing, and thus reduces energy consumption. It also helps to further reduce chip size.
For example, using binary to represent the number 128 requires 8 "bits" of data; using ternary requires only 5 "bits" of data.
Current leakage is a major obstacle to further chip size reduction. Packaging more circuits in a smaller space will make the tunneling effect more serious and increase the leakage current, which also means that the device will consume more power.
Kyung Rok Kim said that if this semiconductor technology is commercialized, it will not only mark a fundamental change in the chip industry, but also be active in industries that rely heavily on semiconductors such as artificial intelligence, driverless cars, the Internet of Things, biochips and robots. influences.
Since September 2017, Samsung has been funding Kyung Rok Kim ’s research through the Samsung Science and Technology Foundation. The Samsung Science and Technology Foundation supports promising technology projects.
Samsung has already verified this technology in the chip foundry business unit.
