I am using an X28C010 EEPROM device and I have a query that is not answered
by the data sheet. I have emailed the manufacturer with my query but haven't
had a reply.
The data sheet states that each byte of the device is guaranteed for a
minimum of 10,000 write cycles. The question I have is 'if the data being
written to the device is the same as the data that is already stored in the
EEPROM then does this reduce the life of the device for that byte?'.
At the moment the device is written to unconditionally before powering down
the system. A collegue is suggesting to me that we could extend the life of
the device by reading each currently stored value and only writing if the
new value is different. However the logic within the chip could be such that
writing the same value as is already stored does not have any life
decreasing effect.
