The architecture of a PC, where information is stored in one module, calculations take place in another, and there are buses for transferring data between them, has become obsolete in the last century. However, effective commercial all-in-one devices have only recently become available. At Nanyang University in Singapore, they are betting on ReRAM "resistive switches" - a new technology that has created a chip that combines data storage and computing in a single element.
Memristors, which are the basis of ReRAM, are good in that they store information by changing the coefficient of electrical resistance. This effect persists even after the power is turned off. In order to activate the memory and start transmitting the signal over the data buses, only a symbolic expenditure of energy is required. Plus a high potential for miniaturization and scaling, when giant logical structures can be recreated in a tiny amount of space.
Singaporean scientists like ReRAM or "memristors" not only for their energy efficiency indicators, but also for the fact that they give a chance to realize an old dream - to say goodbye to a binary system in IT. It is physically very easy to imagine, write down information through the sequence of 1 and 0, but when you start deciphering it, it turns into monotonous Sisyphean work. The ternary system is different - just one more symbol, but what an increase in efficiency!
In the ternary system, there are 0, 1 and 2, and the ReRAM memory just allows you to store data in analog format in three positions with a clear gradient. No energy consumption, no old expensive on / off principle. As effective as it is difficult - at one time in the USSR they far outstripped Western science in this field, but when it came to the creation of applied systems, everything collapsed under a pile of problems.
Even more interesting, ReRAM technology allows you to go beyond three states - with proper calibration, there can be many of them. In theory, this is the key to creating multidimensional memory systems where billions, if not trillions of times more data will be stored and processed simultaneously on a chip of today's size.
