What events happen when we say that a cache at level i is accessed? (I am able to use the cache formulas as given in textbooks and also most of the times, I arrive at the correct answer, but I want to fully understand the basic details.)

My understanding is the following events occur in the duration of an access time

  • The  level i cache memory's RAM is accessed using the data bus.
  • The cache RAM loads the required data in the data bus.
  • The data on the data bus is stored in the level (i-1)th cache.

Is my understanding correct? Is there anything else which happens in the access duration?

Do we include any extra time for STORING the data in the level (i-1)th cache as is done here ?
