2 votes 2 votes Cache to MM transfer always occurs in terms of blocks. And as you may already CPU to cache access is in terms of words. Blocks in MM are usually reffered to as pages and in practise are far more bigger than a block. But from gate pov if it is not explicitly specified then both are equal.
