Even if non-invasive methods do not work, invasive methods could help. For example, the memory control circuit can be modified under a FIB to directly access the reference voltage, the current source or the control gate voltage. Finally, some chips program all the memory locations before applying the erase operation. This makes it almost impossible to extract any useful information from the erased memory. One more thing should be mentioned in connection with hardware security.
