ABSTRACT:
An architecture is described for a single chip microcontroller wherein the microcode stored in the microcontroller's program memory may be easily modified without refabrication or removal of the microcontroller from its target environment. This is made possible by the utilization of a RAM based architecture for program memory instead of the traditional ROM based architecture.
