The idea of combining memory and storage into one device has been around for a long time, but recently, researchers found a way to make UltraRAM a reality.

The idea of combining memory and storage into one component has been around for a long time, but up until now, it was nowhere near becoming a reality. However, that might be about to change.

According to the paper published on this matter , UltraRAM is a technology that would combine the stability and non-volatility of data storage memory with the high speeds and energy efficiency of RAM. Although no such hardware has been produced yet, it should be possible — which is why there already have been attempts to make something along the lines of UltraRAM in the past.

While memory and storage solutions have their similarities, there haven’t been many successful attempts to combine the two. One example of something similar is Intel Optane, which is an alternative to flash memory. However, Intel seems to be walking away from it; the company discontinued all consumer-only Optane products in 2021.

The scientists described the process in their paper, indicating that production on silicon wafers could be well within the realm of possibility. The process includes the use of Indium arsenide quantum wells and aluminum antimonide barriers. Quantum wells are extremely thin layers in which particles cannot move up or down but can move along and across the other two planes. Together, these quantum wells and barriers create a triple-barrier resonant tunneling structure.
