Abstract
A motherboard of a computer system has a video display port, a reprogrammable non-volatile memory, a controller for the non-volatile memory, and a graphics controller circuit for outputting video signals to the video display port. A wired-OR circuit connects the graphics controller circuit to the controller to the port. Thus, the video display port can be used to output video signals from the computer system to a peripheral video display device, and the video display port can be used as an input port to reprogram the non-volatile memory. The present invention also relates to a non-volatile memory device which has an array of non-volatile memory cells and two ports for communication therewith. A first port receives a first communication protocol and interfaces with the array in the first communication protocol. A second port receives a second communication protocol and converts the second communication protocol into the first communication protocol.
