PURPOSE: To obtain a time switch in which low power consumption realization in a communication path memory and the facilitation of the updating of data incorporating an extension bit in a control memory are taken into account. ;CONSTITUTION: While the availability of a communication data writing operation to a communication path memory 3 from a control memory 5 by means of a writing address is controlled by the extension bit, when the communication data from the memory 3 is to be outputted to an output highway 2 by means of a read-out address from a counter 4, the availability of the read-out operation in the memory 3 by means of the extension bit from an extension bit memory 13 is controlled and the wired-OR of the read-out data from the memory 3 is made available on the highway 2 and such data are controlled to be outputted from a gate.;COPYRIGHT: (C)1993,JPO&Japio
