p. 32 of the PDF:
– Simple ECC (e.g., SECDED) cannot prevent all errors

 From wikipedia:  Tests show that simple ECC solutions, providing
 single-error correction and double-error detection (SECDED)
 capabilities, are not able to correct or detect all observed
 disturbance errors because some of them include more than two flipped
 bits per memory word.[1]:8[11]:32
