"Ultralow logic state switching energies of 10−17 J are predicted for 20 nm feature size ULTRARAM memories." Which basically means that they have not yet managed to get UltraRAM working on a 20nm process. Intel made great predictions about Optane memory, as did the developers of STT-MRAM, but all of these technologies have encountered tremendous challenges scaling down to the 7nm and now 5nm process sizes that vendors like TSMC are now selling in bulk. I really hope they're able to come through where previous vendors have failed.
