Honored ContributorWhat configuration are you using? For example a 1GB RAM that has a x32 off-chip interface in half-rate mode will be x128 on the local side. That will result in 26 address lines. That same memory in full-rate mode will appear as a x64 on the local side and expose 27 address lines.
