Abstract:
Actually EEPROM is commonly used to store configuration parameters and operating history information in embedded processors. For example, to record the most recent operating data in case there is a system failure or power loss. This sort of things might require recording data every few seconds [1].
The issue here is that EEPROM works for a limited number of write cycles. After from 100,000 to 1,000,000 (depending on particular chip), some of deployed systems will start exhibiting EEPROM wearout and a field failure might be get. A million writes sounds like a lot, but they go by pretty quickly [1].
