Hi!
Is it possible to calculate the Life of EEPROM based on the number of write cycles?
Is there a particular formula or method to do that?

I need to check the endurance rating of M24M02-DR for specific write cycles and temperatures.

yes, the same way that you would calculate the length of an hour based on the number of minutes in it.

 

Now for a useful answer.

@TS Have you looked at the datasheet?

How will you use that data?

An EEPROM is considered to have failed after any bit won't program or store data. The numbers the manufacturer gives you are statistical. You could get a device that fails earlier or later than the given range; that's the nature of semiconductor devices. Some will fail early due to manufacturing defects, while others may greatly exceed the typical lifetime.

 

Actually since the spec is for MAX endurance any part that lasts 4,000,000 and one cycles is a failure... Only those parts that fail earlier meet the specification.

Write the value to a non-EEPROM register, Once you write the value to an EEPROM register, then read the value back from the EEPROM register and compare to the value in the non-EEPROM register. If they are the same, you were successful.

 

Of interest, do you mean to test the endurance, or calculate the expected ?

this might be of interest,
its for the arduino, but the technique is true of all types.
