Abstract: A resistive memory apparatus including a memory cell array, at least one dummy transistor and a control circuit is provided. The memory cell array includes a plurality of memory cells. Each of the memory cells includes a resistive switching element. The dummy transistor is electrically isolated from the resistive switching element. The control circuit is coupled to the memory cell array and the dummy transistor. The control circuit is configured to provide a first bit line voltage, a source line voltage and a word line voltage to the dummy transistor to drive the dummy transistor to output a saturation current. The control circuit is further configured to determine a value of a second bit line voltage for driving the memory cells according to the saturation current. In addition, an operating method and a memory cell array of the resistive memory apparatus are also provided.

Abstract: A VOIP network phone forwarding device is used to forward a call of an extension to a dual-mode mobile terminal. The VOIP network phone forwarding device comprises a wireless network module, a network interface, a phone connection interface, and a processor. The wireless network module connects to a wireless network for signal transmission with the dual-mode mobile terminal via the wireless network. The network interface is coupled to a modem device for connecting to the Internet. The phone connection interface is coupled to a PBX, which is further coupled to several extensions. The processor is coupled to all the above components. When a dialing source dials a phone call to an extension, the processor forwards this call to the dual-mode mobile terminal via the wireless network or the Internet so that a user can answer this call. A mobile extension communication architecture can thus be realized to let users be able to answer any phone call anytime, anywhere.
