ABSTRACT:
A system for determining whether a memory is connected to a controller in a node of a data network. In order to utilize non-volatile memory elsewhere in the system, it is possible to eliminate the EEPROM which is normally connected to the controller. In order to indicate that the EEPROM is deliberately missing, a pull-up resistor connected to a voltage source is connected to the chip select signal line which normally runs between the controller and the EEPROM. If a high signal is received, the controller knows that the EEPROM is deliberately missing and that non-volatile memory will be provided elsewhere in the system.
