  Resistive Random Access Memory (RRAM) is a type of Non-Volatile Memory (NVM).
In this paper we investigate the sensitivity of the TiN/Ti/Al:HfO2/TiN-based
1T-1R RRAM cells implemented in a 250 nm CMOS IHP technology to the laser
irradiation in detail. Experimental results show the feasibility to influence
the state of the cells under laser irradiation, i.e. successful optical Fault
Injection. We focus on the selection of the parameters of the laser station and
their influence on the success of optical Fault Injections.
