https://en.wikipedia.org/wiki/Memory_address_registerIn a computer, the memory address register (MAR) is the CPU register that either stores the memory address from which data will be fetched to the CPU, or the address to which data will be sent and stored. In other words, this register is used to access data and instructions from memory during the execution phase of instruction.

Memory address register - Wikipedia
https://it.wikipedia.org/wiki/Memory_Address_RegisterIl memory address register ( MAR) in ambito informatico, è un registro della CPU contenente l'indirizzo della locazione di memoria RAM in cui si andrà a leggere o scrivere un dato. In altre parole, il MAR contiene l'indirizzo di memoria del dato a cui la CPU dovrà accedere. Quando bisogna leggere dalla memoria principale, i dati vengono salvati nel ...
