We talked about Resistive Switching RAM, also known as ReRAM, the new memories that would arrive to solve the performance, consumption and space problems of current RAM memories.

The current price problems of RAM, either due to lack of stock or manipulation of manufacturers' prices, in addition to the VRAM stock problems, make it necessary to search for other solutions and there are some that are being developed. The alternatives under development, on the one hand, are the Thyristor RAM (T-RAM), which combines the advantages of DRAM and SRAM memories, in addition, we also find Z-RAM, memories that solve the density problems of the SRAM without losing efficiency. The last solution under development is ReRAM, which could be imposed, as its manufacture and marketing are more viable.

Currently DRAM memories are volatile and this is due to the fact that it is necessary to erase the stored data, several times per second, which is a problem. This is a problem at the energy efficiency level, since it makes them a highly inefficient solution, but it is the most used for the different advantages it offers, such as working speeds or the possibilities of modifying frequencies. Current programs, on the other hand, do not normally make use of hard drives for uploads, they load directly into RAM and force data to be transmitted between processor and RAM constantly.

Volatility and constant data exchange are the factors that Resistive Switching RAM, better known as ReRAM, aims to solve. Memories of this type store data, as if it were an SSD or a pen drive, so they are non-volatile memories. These memristors (so called, also), have a mode of operation quite similar to human neurons, offering more speed, smaller dimensions and less energy consumption, with respect to current DRAMs.

These ReRAM memories have been under development for a long time and are the ones that are best postulated as future memory for processors and that allow them to be integrated into the processors themselves, since it allows the combination of circuits and integrates them in a single package. The great advantage of this system is the integration and development of increasingly smaller systems and improving the autonomy of the devices. Another factor is the improvement of the power of computers and mobile devices, making them faster. The ping or delay between the communication of the processor and the RAM is also suppressed, since it is all integrated in the same system. The researchers say that by reducing these latencies, the number of data processing is increased.

TERNARY SYSTEM

The great novelty of the ReRAM is that it would work through the ternary system, or what is the same, in three states: 0, 1 and 2; compared to the binary system that only works in two states: 0 and 1. The binary system presents problems and limitations and the jump to this ternary system, which is not a completely analog system, would make it possible to overcome these problems, allowing higher powers of communication and more possibilities in the states, also allowing greater precision. The researchers are also working on a ReRAM that is operational in more than these three states, something that is complicated, but that would increase the possibility of computing and storing data. Researchers collaborate with developers and electronics companies to bring these advances to the commercial segment.
