Abstract
A method and a circuit generate a pulse synchronization signal (ATD) for timing the memory cell read phase in semiconductor integrated electronic memory devices. The pulse signal (ATD) is generated upon detection of a change in logic state of at least one of a plurality of address input terminals of the memory cells. The method consists of duplicating the ATD signal into at least one pair of signals and propagating such signals through separate parallel timing chains at the ends of which the ATD signal is reinstated, the chains being alternately active.
