Thermal wear? I thought it was mostly based on write cycles. How can that be 'thermal'?

The write cycles are realised by moving electrons through a material. This creates heat, which leads to gradual degradation of the material.

Does the individual gate get that much hotter than the rest of the device?
If I keep my SSD 40 degrees cooler with a freezer, will it last an indefinite number of write cycles?

I just looked this up, and it turns out I was completely wrong about how the wear is caused. Apparently it’s due to a build-up of electrons remaining in the floating gate over time, and not general thermal wear. It turns out that heating can even reverse this wear.
