Does write memory wrong can prove that it may be electrical fault?

Question

I hear a story that: A man who new a huge memory and set all of them to be zero and then read them and find there are some are not zero,so it prove that it may be electrical fault?

Does it right?Why?

Answer 1

Your question isn't very clear but it sounds like you are asking if you set all your memory to zero if it's possible to later read back different values due to an electrical fault?

Yes, that's certainly possible. Power spikes can certainly corrupt memory as well as a lot of other things. Some examples here
