Abstract
A method for detecting a data bit inversion (DBI) error in a memory system is disclosed. The method and system comprise calculating an error correcting code (ECC) from each of the 8 beats of a burst of data such that no more than one bit per byte is included in each ECC calculation. The method and system further include determining if there is an inversion of one byte in the burst.
