Abstract:
A system for replacing a page stored in system memory when reading the page incurs a multiple-bit error. Upon reading a page in system memory for which a multiple-bit error is detected, backup data in flash memory is loaded into a redundant page in the system memory, and a re-mapper is configured so that future accesses to the page are redirected to the redundant page.
