No, they're referring to bit rot on flash storage due to slow leakage of the charge that represents the data. It occurs on long time scales, definitely years. But the more bits per cell (SLC vs TLC vs QLC), the more likely it is.

Could not the same be said of the magnetism of the bits on spinning rust? What's the shelf life of data on an HDD? Tapes also have magnetic charge, but are designed to be "unrefreshed" for longer periods of time.
- labawi 5y agoTapes and HDDs are magnetic. Flash and DRAM is electric. It is easier to create magnetically stable structures (magnets) than non-leaking capacitors. Flash has a better insulator than DRAM, but it wears out with use and leaks more with higher temperature, densities, less margin with more bits per cell...
