Abstract
An integrated circuit chip comprising an integrated circuit made in a semiconductor substrate, an information write-register circuit having a plurality of gate-controlled components, such as MOS transistors or capacitors, said write-register being integrated into said circuit yet individually addressable; said components having a gate insulator geometry locally susceptible to electrical conductivity upon applying overstress voltage pulses between said gates and said substrate, whereby information can be permanently encoded into said write-register; and a plurality of level shifter circuits to supply said pulses selectively to said component gates according to stored data and controlled by enable commands, said level shifters being integrated into said circuit.
