XOR is true only when inputs differ. That means if inputs are the same, then it outputs false (0) or whatever you call it. Then we perform OR operation between those outputs. So if the result is 0 then addr1 and addr2 is equal. > This way, -for the code to work- memory should be everytime unaligned !=0.
