DRAM problems used to be a common thing, at least AFAIK in the 90s up to early 10s. I wonder if that still the case or is it now a non-issue for the first 5 years of usage. Our Watch, iPad, Phones all have more memory than old computers. Even Apple Watch Ultra now has 4GB of memory which I thought was crazy.

If it is not, how would all these appliance with memory doubt with bad memory?
