1. Method of writing a tagging character into a memory (1) formed by cells for storing electrical charges, characterized in that it consists, during the production of the circuits scheduled to cooperate with the said memory, in dividing the memory space into at least two regions of which one is intended to receive a tagging character, in charging a particular number of cells for charge storage forming the tagging region with a quantity of electricity which is smaller than or equal to that utilized to write binary data into the other region or regions, then in isolating the region allocated to the tagging character from the write circuits to the memory by interposing between the memory control means and the memory such means as to authorize access to the tagging character in the read mode and preventing said access in the write mode. |
