Method and system for correcting errors in read-only memory devices, and computer program product therefor

摘要

A system for correcting errors in read-only memory devices by means of memory patches, wherein patch data is used as read data in the place of erroneous data stored at a given location in the memory. The system includes a processing core, such as an ARM processor, adapted to perform opcode accesses as well as data accesses to memory addresses being patched. The processing core is configured for providing different patch-data for correcting errors depending on whether it is performing a code access or a data access to an address being patched.
