Atomic /Electro-Chemical Switches - Pro TiOx switching is controlled by oxygen vacancies What can we do with these devices: Memory? How reproducible are these switches? How fast do they switch? …… Adjunct technology in context with CMOL or other hybrid approaches Net: This was a research report but not a summary on the opportunity or capability of these devices! Metric missing

Atomic /Electro-Chemical Switches - Con Mechanism: Ionic transport plus chemical reaction (the slower process determines the switching speed) -> formation of atomic bridge Application: Memory, logic not quite clear –Switching time slow ~ 100ns (reported in array 4-30us, 1.1V; 50ns, 0.6V) –Cycling low 1E11 –Data situation confusing to allow projection (not quite clear what is intrinsic material property and what is process related) Challenge: reliability, switching speed, endurance Ion mobility small number limits migration time ~ 1ns New logic gates required for this device: fabrics need to be integrated with I/Os, density requires default tolerant architectures, what happens with defect driven lkg in the fabrics?

Atomic /Electro-Chemical Switches - QA Q: If diffusion is grain boundary what about scalability A: not quite clear if it is Q: Switching voltage pretty high about a volt A: Yes they are high. Not quite clear if this can be reduced and maintain a high on/off ratio Q: Will power in these arrays dominated by array and not by overhead A: Depends on array architecture
