<p>A method of fabricating an integrated circuit includes the steps of fabricating storage means 2 in the integrated circuit, fabricating first connection mean 3-14 which so connects a signal source A, A in the integrated circuit to the storage means that the signal source, when active, sets the state of the storage means for providing information about the integrated circuit in accordance with the arrangement of elements of the first connection means and fabricating second connection means 15 connected to the storage means for enabling the reading of the state of the storage means. Pairs of elements 3,4; 7,8 and 11,12 lie in three superposed conductive layers of a semiconductor substrate. A programmable storage means 1B instructs a principal functional part 1 of the integrated circuit to read the contents of the data storage means 2. The data read from the storage means 2 provides information such as a number indicating that the integrated circuit is a revised version or the information may be the fabrication date of the integrated circuit.</p> |
