Endurance figures come from actual testing with their 20um version. Retention is based on looking at the decay over 14h. Since it decays to begin with then plateaus they look at fitting a line to it from some time before the plateau (otherwise the answer is "infinite years") which gives 10^7 hours.

- DoctorOetker 3y agoI would assume they would have a couple of such devices running since publication till now. Instead of >24 hours they probably know the endurance after about 500 days today, allowing for more convincing extrapolations towards 10^7 hours. It is unclear from the article if these plots are tests of individual memory cells or a large collection of cells. Any serious attempts would involve an array of cells so a million such graphs can be plotted together etc.
