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

- Dylan16807 8y agoDoes 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?
- 0db532a0 8y agoI 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.
