Yes and No, a system that can only access 4GB of virtual and real memory is a 32-bit system, not 64-bit. Just think back all the way to the 8-bit platforms, has the amount of memory that you can access ever corresponded to the number of bits advertised by the platform? Mainframes, YES. Intel, no.
This statement might sound more accurate if you left off virtual. Data spaces increase the amount of virtual storage available to a program running on an ESA/390 (31-bit) platform to numbers *far* in excess of 4G! By default, the limit on the amount of virtual data space storage that may acquired by an unauthorized program is 2^24 megabytes.
