Questions and Answers
If the processor needs to read a memory location, it sends a read request via the control bus, along with the address of the memory location via the address bus. These operations happen at the [same] time (i.e. in the same clock cycle).
Depending on how long it takes to access the memory, the processor then receives the contents of that memory location via the data bus, after a number of [clock] cycles.
If the processor needs to write to a memory location, it sends a write request via the control bus, along with the address of that memory location via the address bus and the data that needs to be stored via the [data] bus.
