How do out memories stay intact even when cells/neurons are completely replaced?

The human body replaces all of its cells every couple of months, right? Well, how is information like memories in neurons or scars on the skin kept through the replacement? Wouldnt the scar eventually become same old skin, or the neuron become a new cell to be engraved with information- as if it was a computer file being overwritten? Some scars do fade, i guess. But others seem to stay no matter what you do, even after decades when the cells have surely been replaced.

Neurons aren't replaced like other cells. There is very minimal neuronal regeneration in the brain. Further, our current understanding is that memories are stored at the circuit level, not the single cell level. So disruption to any part of the circuit could impact a memory. Unfortunately, even the process of accessing the memory allows the opportunity to corrupt it.
