The ECC memory page has the same non sensical statement:

> Error-correcting memory controllers traditionally use Hamming codes, although some use triple modular redundancy (TMR). The latter is preferred because its hardware is faster than that of Hamming error correction scheme.[16] Space satellite systems often use TMR,[17][18][19] although satellite RAM usually uses Hamming error correction.[20]

So it makes it seem like TMR is used for memory only to then back off and say it’s not used for it. ECC RAM does not use TMR and I suggest that the Wikipedia page is wrong and confused about this. The cited links on both pages are either dead or are completely unrelated, discussing TMR within the context of fpgas being sent into space. And yes, TMR is a fault tolerance strategy for logic gates and compute more generally. It is not a strategy that has been employed for storage full stop and evidence to the contrary is going to require something stronger than confusing wording on Wikipedia.
