ECC is able to recover from multib(i|y)te errors

ECC is able to recover from multib(i|y)te errors

While single bit data errors can be corrected via ECC, multi-bit data errors cannot.

It depends how log the data and the ECC code are. Longer ECC provides capability to correct (and detect) more bites.

in theory yes, but you are forgetting that we are talking about a very standardized use of ECC, namely what is implemented in RAM and memory controllers. that implementation only corrects single-bit errors
