We know a CPU connect with Memory with Address Bus, Control Bus, Data Bus.
When CPU want to write
11110000 into Memory
0x0001, it will
first, Address Bus locate to Memory address.
then, Send Control Bus instruction(write), to Memory.
at last, CPU will send the data
11110000 to Memory.
I want to know why Memory can use Control instruction and Data to update the memory data. Is there any register and some instruct for update memory data in Memory device?
