Abstract
A first plurality of address bits is provided to an address bus during a first time period. At least one banking address bit or at least one non banking address bit is selected according to a banking control signal, the selected bit being part a second plurality of address bits. The second plurality of address bits is multiplexed onto the address bus during a second time period. A first selector circuit receives a first and second group of address bits for a memory and outputs the first and second group during a first and second time period, respectively, according to a first select signal. A second selector circuit provides a subset of the second group to the first selector circuit, the second selector circuit selects a banking address group or a non banking address group as the subset according to a memory banking enable signal.
