Doped hafnium oxide ferroelectric semiconductor memory/ logic gate resolves memory (density, efficiency)/ processor (speed) tradeoff

"rapid electrical polarization switching, non- volatile, data/ CPU/ memory on same chip... 3D Vertical Integration without heat-induced degradation... 4X increased storage capacity, sub-1.0V which is 60% lower for data-intensive tasks, lower latency... direct challenge to high-bandwidth memory (HBM)... because hafnium oxide already standard material in CMOS fabrication, can be integrated into existing semiconductor foundries with minimal retooling"
