Furthermore, manufacturers can stack the chips for higher densities.
Conversely, the chalcogenide material in SOM switches between conductive and resistive states to store data.
Of course, not just any chalcogenide composition will do the trick.
The materials must have optimal properties for memory performance and selector functionality.
To find the right candidate, Samsung used advanced computer modeling to predict the potential of various material combinations.
The company estimates that over 4,000 potential chalcogenide mixtures could work for SOM.
Samsung claims its modeling techniques establish clear screening criteria to identify the most promising SOM material blends.
The team plans to present its findings at the International Electron Devices Meeting in December.
