IC Identification and Reliability Verification Using Ring Oscillator Based Physical Unclonable Function and Aging Detection Circuit |
| abstract |
One feature relates to an integrated circuit "IC" comprising: a first plurality of ring oscillators (318) configured to implement, in part, a physically unclonable function "PUF". The IC further includes a second plurality of ring oscillators (320) configured to implement in part an aging sensor circuit, and also includes a second plurality of ring oscillators coupled to the first plurality of ring oscillators (318) and the first A ring oscillator selection circuit (312) for two or more ring oscillators (320). The ring oscillator selection circuit (312) is adapted to select at least one from the first plurality of ring oscillators (318) and/or the second plurality of ring oscillators (320) At least two ring oscillator outputs (322n) of In particular, the ring oscillator selection circuit (312) is generally shared by the PUF and the aging sensor circuit. Also, the IC may further include an output function circuit (314) adapted to receive and compare the two ring oscillator outputs and generate an output signal (326). |
