| Outline of Final Research Achievements |
In this project, we have developed countermeasures for malfunctions of LSIs and an estimation method for performance degradation by aging, which are caused by environments of LSI usage.
(1) Behaviors of flip-flops (FFs) by power supply noise are analyzed first, and then, we identified that the error of the bit-flip like memories occurs. We also clarified mechanisms of error occurrences, and then developed circuit structures of FFs to prevent error occurrence.
(2) We developed a method for estimating aging of LSIs by using two kinds of ring oscillators. The method could estimate aging from the transistor level to the circuit level.
