Abstract
A method and apparatus for removing soft errors in a memory element by providing dedicated hardware associated with each memory element which monitors for soft errors as data is read from the memory element. Further, when a soft error is detected, the dedicated hardware may correct the soft error and may further initiate a write operation and over-write the corrupted data word with a corrected data word. This may be accomplished without any intervention by the system.
