The Memory Control Ship Is Just a Dcode

The processer puts a unique address consisting of 32 bits on to the address bus, which is then sent over to the memory controller sits with the ram. The memory controller decodes this address, and from it generates a set of four n signals that go out and either enable or disenable the appropriate tri state buffers. Each one of the flip flops in all the registers will already be connected up by its own wire to to the corresponding bit wire along the data bus. But i need to have four billion separate wires coming out of my memory control ship because i need to be able to individually access each one of those registers depending on what address was sent in.
