ECC (error correction code) and write cycling
Most M95128, M95128-W and M95128-R devices offer an ECC (error correction code) logic
which compares each 4-byte word with 6 EEPROM bits of ECC (the list of concerned
devices is defined in
temperature
erroneous during a read operation, the ECC detects it and replaces it by the correct value.
The read reliability is therefore improved by the use of this feature.
Note however that even if a single byte has to be written, 4 bytes are internally modified
(plus the ECC bits), that is, the addressed byte is cycled together with the three other bytes
making up the word. It is therefore recommended to write by packets of 4 bytes in order to
benefit from the larger amount of write cycles.
The maximum number of write cycles is qualified at 1 Million (1 000 000) write cycles, using
a cycling routine that writes to the device by multiples of 4-byte packets.
