A reference voltage supply apparatus and a driving method thereof in a ferroelectric memory device provide a reference voltage stabilized against the imprint effect thus maintaining reading reliability of the device. In the reference voltage supply apparatus (e.g., using a non-switching capacitance of a ferroelectric capacitor), a reference cell is constructed of a ferroelectric capacitor and an access switch, and provides a reference voltage to read data from a memory cell. In an active mode, the reference cell stores data of a first logic state (e.g., corresponding to the non-switching capacitance of the ferroelectric capacitor), in the reference cell, and then supplies, as a reference voltage, the voltage corresponding to the data of the first logic state to a bit line; and in a stand-by mode, a reference voltage controller stores (writes) data of a second logic state (opposite to the first logic state), into the reference cell.

An ECU controls an opening degree of an EGR gas switch valve based on a temperature of intake air and a load state of an engine in such a manner that a temperature of exhaust gas becomes a suitable temperature, which is suitable for regeneration of a particulate filter arranged in an exhaust gas passage. In this way, cooled EGR gas, which passes a main passage, and hot EGR gas, which passes a bypass passage, are appropriately mixed. In a case, where reliability of an EGR valve cannot be maintained, EGR cut is performed.

A printer 240 calculates the amount of ink used only for printing as a number of discharged ink shots, and sends this shot count with the printer serial number and ink cartridge ID to a server 220. The server 220 saves the shot count, printer serial number, ink cartridge ID, and an error correction code as status information. The server 220 or server upstream from the server 220 can reliably determine the number of ink shots used by the printer 240 only for printing from this status information.

A master node transmits a probe packet for checking a condition of a network in a ring in both directions thereof to detect the occurrence of a fault on the ring. A slave node increments a hop count included in the received probe packet, transmits it to an adjacent node configuring the ring, and transmits a hop count report packet to the master node. The master node detects a fault on the ring based upon a fact that the master node does not receive the probe packet transmitted by itself. Further, the master node detects the occurrence of multiple faults and the recovery of at least one of the multiple faults based upon the sum of maximum values of hop counts in the hop count report packets received from both directions of the ring and transmits a packet for prompting the update of the database for packet transfer.
