Ashok H Someshwar, Kenneth A Lies, Jeffrey R Teza: Modular input/output system. Texas Instruments Incorporated, Rene E Grossman, Leo N Heiting, Melvin Sharp, February 7, 1984: US04430584 (46 worldwide citation)

A memory mapped I/O scheme treats each I/O buffer as a memory element which can be addressed, written into or read from. Each I/O buffer has its own memory address decoder which eliminates the need for special select/control lines for each buffer and enables the use of a single address/data bus. Thu ...
