Abstract
A method provides the capability to maintain integrity of a data image stored by computing a hash value ('digest') of the data image and comparing the hash value computed for the data image with a hash value computed for the data image and kept in a non-volatile area of memory. Bit flips in the data image that are a result of memory hardware errors reveal themselves as differences in the digest computed for the data image and the computed digest for the data.
