摘要:
The invention discloses an integrated circuit (10) for securely storing a codeword. The value of the codeword is dependent on the mobility (μA, μB, μC) of at least one transistor (TRA, TRB, TRC) of the integrated circuit. The invention further discloses a reader means (15), a method for determining the value of the codeword from the integrated circuit (10), and a method for altering the value of the codeword.
摘要:
The invention provides a FET device (1) with a channel region (2) with a trapezoidal shape in which the linear drain edge (7) is larger than the linear source edge (8). In this way the equality or matching of the DC parameters of two or more FET devices (1) may be improved with respect to rectangular shaped FET devices (100) while simultaneously maintaining a comparable current capability. Alternatively, the total device area of the FET device (1) may be reduced with respect to the rectangular shaped FET device (100), thereby reducing the capacitive loading while maintaining a similar equality or matching of the DC parameters of two or more FET devices (1).
