Yes, in a simplified processor / model, the address calculated by the instruction is placed on the address bus, if it is a record, then the data goes to the data bus, often there is a strobe to write some indication of the memory that this is a write operation, as well as some way to turn on the memory, that it is actually a memory loop. To simplify the logic, sometimes the data bus and even the address bus can do anything and only work if the correct switching on / strobe is present.
