1. A matrix comprising a plurality of volatile switches, each of said volatile switches comprising an active layer made of an ovonic threshold switching (OTS) material, the plurality of volatile switches being divided into first and second groups in such a way as to form a message,
each of the volatile switches of the first group having been initialized beforehand by an initialization voltage,
none of the volatile switches of the second group having been initialized beforehand,
said message being formed by the initialized or non-initialized states of each of the switches of the matrix.
