The architecture of the PC, where information is stored in one module, calculations take place in another, and there are buses for data transfer between them, morally obsolete in the last century. However, effective commercial devices “all-in-one” became available only recently. At Nanyang University of Singapore, they rely on “resistive switches” ReRAM, a new technology that has made it possible to create a chip that combines data storage and computational processes in one element.
The memristors underlying ReRAM are good because they store information, changing the coefficient of electrical resistance. This effect persists even after the power is turned off. It takes only symbolic energy costs to activate the memory and start transmitting the signal across the buses to the data. Plus, high potential for miniaturization and scaling, when giant logical structures can be recreated in a tiny amount of space.
ReRAM or “memristors” like the Singaporean scientist not only for their energy efficiency indicators, but also because they give the chance to realize an old dream – to say goodbye to the binary system in IT. Presenting, writing information through the sequence 1 and 0 is very easy physically, but when you begin its decoding, it turns into a monotone Sisyphean work. Whether the triad system is just one more symbol, but what is the efficiency gain!
In the ternary system, there are 0, 1 and 2, and the memory type ReRAM just allows you to realize the memorization of data in an analog format in three positions with a clear gradient. Without energy costs, without the old costly principle of “on / off”. As effective as it is difficult – at one time in the USSR it has far outstripped Western science in this field, but when it came to creating application systems, everything collapsed under a pile of problems.
What’s more interesting, ReRAM technology allows you to not limit yourself to three states – with proper calibration there can be many. In theory, here it is, the key to creating multidimensional memory systems, where today’s chip will be stored and processed simultaneously in billions, if not trillions times more data.
