A 64-bit OS can address more than 4 GB RAM. 32-bit OSs generally can't. To oversimplify things a bit, numeric data types in a 64-bit OS are larger (64-bit vs 32-bit) to take advantage of the increase in register size. So, storing the same information in a 64-bit OS takes more memory than it does in a 32-bit OS. But, this is outweighed by the ability to address more memory in the first place. So, for example, on a 32-bit OS a JVM can't really address more than 1.5 GB RAM (if even that), but on a 64-bit OS a JVM can address significantly more RAM so it doesn't really matter that it needs more memory in the first place.
