Abstract

PURPOSE:To prevent the destruction of data by reading the data from another memories in an electronic exchange when the data are written to one of plural numbers of memories. CONSTITUTION:A CPU21 gives an address for reading of switching memories 33, 35 and 37 based on sent switching data. A control memory 23 stores temporally the address for the reading. A read/write controller 27 executes the action control of the switching memories 33, 35 and 37 successively corresponding to the instruction of a counter 25. A read/write controller 29 executes the switching of the reading and writing of the switching memories 33, 35 and 37 corresponding to the instruction of the counter 25. A parallel/serial converter 41 converts the voice data of a parallel type read from the switching memories 33, 35 and 37 and sends the data to an output PCM highway 45.
