ABSTRACT:
A multivibrator includes a first data transfer port that receives, as input, multivibrator input data. A first, master, latch cell is connected on the output side of the first transfer port. A second, slave, latch cell is connected thereto through a second data transfer port placed between the first and second latch cells. Each latch cell includes a set of redundant data storage nodes for storing information in at least one pair of complementary nodes and circuitry for restoring information in its initial state, after a current or voltage spike has modified the information in one of the nodes of the said pair, on the basis of the information stored in the other node. The nodes of each pair are implanted opposite one another in a zone of a substrate defining the latch cell.
