64bit version can work with more than 4GB of memory.

On 64bit, a memory pointer is 8 bytes instead of 4 as on 32bit. The same 
applies to 'long' type which has the same size of the pointer on each 
architecture. From here you get more memory usage on 64bit, because many 
internal structures hold pointers or long values.

Cheers,
Daniel
