Abstract:

Secure systems rely on encryption keys to be stored safely. However, it has been shown that popular storage means such as DRAM or PROM possesses vulnerability to physical cryptographic attacks. This work proposed an on-chip secure 10-kb EEPROM with adjustable programming voltages using charge trapping mechanism. The on-chip feature allows encryption keys to be stored with the processor minimizing observability. The use of die dependent programming voltages enables the optimization of data retention time verses memory lifetime. A quick future view on modeling EEPROM lifetime and data retention time tradeoff is given as well.
