I believe the first one is just an I/O constraint that works the same way as set_input_delay. (I always forget the BEFORE/AFTER difference, although they are opposites).

Are mem_data and mem_addr I/O pins? If so, set_max_delay should work fine. Remember that if you also have any set_input/output_delay constraints on those ports, they will be added into your set_max_delay analysis.
