There was nothing wrong with Optane (I'm talking about non-volatile memory, it is important because there were a few products under Optane name) I believe that was/is impressive tech. You could have disk and ram in one stick aka kinda unified memory. Think of it: instead of purchasing RAM+Disk, you purchase one stick and configure it as e.g 40% of the capacity works as a disk and 60% as a "RAM". But saying that they "cancelled" doesn't tell the whole story. IIRC: they couldnt find a fab which would produce them after Micron sold their fab.
