SoftECC is software memory integrity checking agent. SoftECC repeatedly computes page-level checksums as an efficient means to verify that a page's contents have not changed. Memory errors that occur between two checksum computations will cause the two checksum values to disagree. Legitimate memory writes also cause a change in checksum value, so a page can only be protected during periods of time when it is not being written to. Preliminary measurements with an implementation of SoftECC in the JOS kernel on the x86 architecture show that SoftECC can halve the number of undetectable soft errors using minimal compute time.
