Most EEPROM’s utilize some variation of the
“Floating Gate Technology”
A positively charged gate is read as a logic 0.
Most EEPROM’s have a RESET or Write Protect input, when set active, all erase/writes operations are blocked.
Monitor Supply Voltages and provide a RESET signal
when the voltage drops below a pre-described level
A robust hardware and software design, along with a contingency plan should corruption occur, can greatly minimize the risk of system failure due to data corruption in a EEPROM.
