"Future semiconductors may perform logic with 0, 1, or 2 instead of the current binary system of 0 and 1," reports ZDNet:A South Korean research team has successfully realised an energy-efficient ternary metal-oxide semiconductor on a large-sized wafer. Professor Kyung Rok Kim of UNIST's Electrical & Computer Engineering Department and his team successfully created a semiconductor that operates in a ternary logic system instead of the current binary... Using the ternary system of 0, 1, 2 lessens the amount of information semiconductors need to process and does it faster, resulting in less power consumption, the team said. It will also help in miniaturising chips further. For example, to express the number 128 in the current binary system, 8 "bits" will be required. With the ternary system, only 5 "trits" will be required.... Samsung Electronics has been backing Kim's research since September 2017 via its Samsung's Science & Technology Foundation, which offers grants for promising technology projects. Samsung is currently verifying the technology at its foundry business-run fab.
