Question

Explain register bus and memory transfers in detail

Answer 1

The address register (AR) is used to select a memory address, and the data register (DR) is used to send and receive data. Both these registers are connected to the internal bus. DR is a bridge between the internal BUS and the memory data BUS.
Memory can also be connected directly to the internal BUS in theory.
Diagram showing connections to memory unit. M[AR] ← DR DR ← M[AR]
