Storing a word in memory - computer architecture, Computer Engineering

Storing a word in Memory:

That is similar process with fetching a word from memory.

  • The required address is loaded into the MAR
  • After that data to be written are loaded into MDR, and a write command is issued.
  • If we suppose that the data word to be stored in the memory is in R2 and that the memory address is in R1, the Write operation needed the following sequence:
  • MAR - [R1]
  • MDR -[R2]
  • Write
  • Wait for the MFC

Move R2, (R1) requires the following sequence (signal):

R1out, MARin

R2out, MDRin. Write

MDRoutE,WMFC
