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 address length.
Also, what is LTC128B and (.128) means ?

I believe your question would be better answered by the Nsight Compute team.
