17 / 39 page M24128, M24C64, M24C32 Device operation 17/39 Figure 9. Write mode sequences with WC = 0 (data write enabled) 4.9 ECC (error correction code) and write cycling The M24128 and M24C64 in UFDFPN8 (MLP) 2 × 3 mm package and the M24128 in WLCSP package offer an ECC (error correction code) logic which compares each 4-byte word with its six associated EEPROM ECC bits. As a result, if a single bit out of 4 bytes of data happens to be erroneous during a read operation, the ECC detects it and replaces it by the correct value. The read reliability is therefore much 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 word), 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. All M24C32, M24C64 and M24128 devices are qualified at 1 million (1 000 000) write cycles; the M24128 and M24C64 in UFDFPN8 (MLP) 2 × 3 mm package and the M24128 in WLCSP package are qualified (at 1 million write cycles), using a cycling routine that writes to the device by multiples of 4-byte words.
