Security processors typically store secret key material in Static RAM, from which power is removed if the device is tampered with. It is widely known that, at temperatures below −20°C, the contents of SRAM can be ‘frozen’; therefore, many devices treat temperatures below this threshold as tampering events. We have done some experiments to establish the temperature dependency of data retention time in modern SRAM devices. Our experiments show that the conventional wisdom no longer holds and that data remanence can be a problem even at higher temperatures.

Data remanence affects not only SRAM but other memory types as well, like DRAM, UV EPROM, EEPROM and Flash. As a result, some information still can be extracted from MCU memory code that has been erased. This could create many problems for secure devices which assume that all the sensitive information is gone once the memory is erased.
