Abstract: The invention concerns a programmable integrated electronic system including an array of identical cells (53). Each cell includes functional components (530) capable, when they are correctly connected, of executing a given function, and programmable connecting means (a to h) for on the one hand connecting the functional components to each other and on the other hand connecting the cell to its neighbours. The present invention is characterised in that the system includes means of storing a first data item which defines the function of each of the cells in the array and in that each cell has means for extracting, from this first data item and its location the network, the programming word for its own function. In addition, means are provided for effecting the test of correct functioning of each cell and for reconfiguring the array where there are defective cells.
