Shared memory: LDGSTS Async copy understanding problem

Hello all, I’m trying to model the shared memory in Ampere Architecture. However I feel like the SASS and the nsight profiling are not obvious.
As shown in the attached picture, I used nvbit tool to get the memory trace. But the addresses doesn’t contain the same addresses lengths .
Also, what is LTC128B and (.128) mean ?

I’m not an nvbit expert so I would recommend reaching out to that team. Perhaps on their github page. It could be that the addresses are just omitting leading zeros which would cause them to be different lengths.
