In a telecommunication system, especially a telephone system having at least one electronic computer controlled telephone exchange, in its turn having time-space type switches, including a number of memory devices in the form of matrices, a method and an apparatus for transferring, via inputs and outputs of the memory devices, speech and data information in binary form between subscribers connected to the exchange. To considerably reduce the power consumption of the memory matrix as a whole, devices are provided to activate only those memories, which, for the moment, are intended to emit a corresponding output signal after that data has been written into same, and to cut off those portions of the memory matrix, which are not used for emitting output signals, in that no information is written into those, thus, not activated memories.
