In a 32-bit program an address is a 32-bit value. In a 64-bit program an address is a 64-bit value (although only the low 48 bits are used). In a linear address space, the possible address space is 4GB. One note is that many hardware items are memory mapped to addresses.
However, this will not totally solve the Fedâs problem. Even when it was paying the banks 0.25% interest on reserves, the effective federal funds rate (the rate at which reserves at the Fed were actually being traded) was below 0.25%.
