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%.

Definition: The prime interest rate is what U.S. banks charge their best customers. It's usually the best loan rate available to non-banks. It's also called the prime lending rate, the prime rate, or even just prime. Banks base the prime rate on the federal funds rate. That's the rate banks charge each other for special overnight loans. They borrow fed funds from each other to fulfill the Federal reserve requirement each night. For example, o December 15, 2016 the Federal Open Market Committee raised this rate to 0.75 percent.
