How many capacitors do you have that can hold their charge for 55 years?
Every EEPROM is basically that, and they're designed for data retention of around 100 years. I imagine it wouldn't be hard - embed two metal plates in glass?
You don't check the eeprom value by flowing current thru the cell as you do with cap
