A selectively called wireless receiver includes a wireless unit 2 for demodulating a received wireless signal and a control unit 1 for allowing a message to be displayed and allowing an alarm sound to be generated based on the signal demodulated by the wireless unit. The control unit 1 has a integrated circuit and an external memory 11. The integrated circuit includes a CPU 100, a decoder 101, an internal memory 102 and a transfer gate 106. The decoder 101, internal memory 102 and transfer gate 106 are connected mutually by an internal address/data bus S. The external memory 11 is connected to the transfer gate 106 in the integrated circuit 10 by an external address/data bus T. The transfer gate 106 is opened only when the external memory 11 is accessed, thus reducing noise. |
