techspot Non-Volitile RAM being developed by Samsung

Samsung is working to accelerate the development of a promising new memory technology called Selector-Only Memory. The latest tech combines the non-volatility of flash storage and DRAM's lightning-fast read/write speeds, making it a potential game-changer. Furthermore, manufacturers can stack the chips for higher densities.

 

The core concept behind SOM is using unique chalcogenide materials that perform double duty as both the memory cell and the selector device. In traditional phase-change or resistive RAM, you need a separate component, like a transistor, to act as the selector to activate each cell. Conversely, the chalcogenide material in SOM switches between conductive and resistive states to store data.

I had to look up the term "chalcogenide material".

These materials have strong resonance bonding in their respective crystalline states and that results in their distinctive optical properties (Gong et al., 2021). All of these chalcogenides share covalent bonding due to small differences in electronegativity, which results in both phases being non-volatile. This is an advantage for certain applications where constant energy input will not be required to maintain one of the states.

Definitely something that could have a big impact if it comes to fruition.
