A method for the correction of an erroneous bit in a string of bits includes providing, in the string of bits, for a first parity bit computed from the other bits of the string of bits at a point in time when the erroneous bit was valid. The correct value of the erroneous bit is computed by using the other bits of the string of bits comprising the parity bit. The erroneous bit is then replaced by its correct value. The method is applicable to error correction circuits in EEPROM memories.
