Popis: Every year, smarter and more complex attacks compromise electronic systems. Unauthorized access to the secure keys stored within nonvolatile memories is a concerning problem affecting secure applications. This paper presents an RRAM architecture secured against firmware and physical attacks. If a hack attempt occurs, and taking advantage of the threshold behavior of fast RRAM devices, this solution erases the whole memory in a single process preventing the sensitive information to be accessed while avoiding the circuit destruction. Complementing encryption solutions, our architecture provides extra-protection mechanisms that, even deprived from the main power supply, prevent the most sensitive information to be leaked.
