Abstract
The invention relates to the asynchronous communication of data in complex integrated systems, be it inside integrated circuit chips or between integrated circuit chips, for example in a compact stack of chips. According to the invention, the transmission is done on a single conductor of exchanges. The data are transmitted on this conductor in the form of at least three levels of potential, the first level representing a first value of data item transmitted, the second representing a second value of data item transmitted, and the third representing an inactive level. An acknowledgment signal is transmitted on the same exchange conductor as the data. This signal is preferably sent by the receiver in the form of the forcing of the exchange conductor by the receiver to the inactive potential level, the sender detecting this forcing.
