Abstract

L'invention concerne les générateurs d'impulsions. Un circuit destiné à engendrer des impulsions successives apparaissant sur des lignes distinctes et ne se chevauchant pas comprend essentiellement trois bascules bistables FF1, FF2, FF3. Ces bascules sont placées initialement dans un premier état, et sont branchées de façon que la bascule FF2 ne puisse changer d'état qu'après la bascule FF1, et de façon que la bascule FF3 ne puisse changer d'état qu'après la bascule FF2. Application aux circuits d'écriture/lecture de mémoires.
