Abstract
An apparatus dynamically decodes memory addresses while supporting memory map options that require different memory bits which are dependent upon the memory address. A current CPU address or an address stored in an expanded memory specification (EMS) register is selected as the defining address. This defining address is then decoded by one of twenty-five (25) memory map options available. The resultant decoded signal drives select lines of a multiplexer whose output drives memory address lines to on-board banks of DRAMS.
