Abstract
In the area of fault attacks, lasers are a common method to inject faults into an integrated circuit. Against the background of decreasing structure sizes in ICs, it is of interest which fault model can be met with state of the art equipment. We investigate laser-based fault injections into the SRAM-cells of block RAMs of two different FPGAs with 90nm and 45 nm feature size respectively. Our results show that individual bit manipulations are feasible for both, the 90nm chip and the 45 nm chip, but with limitations for the latter. To the best of our knowledge, we are the first to investigate laser fault injections into 45nm technology nodes. We provide detailed insights of our laser equipment and the parameters of our setup to give a comparison base for further research.
