ABSTRACT:
A method and apparatus is described herein for managing bad blocks/sectors in a nonvolatile memory. Upon detecting an input/output fault to a target block in a nonvolatile memory, the target block is remapped to a spare block, if the block is predicted as a bad block. Remapping is done for blocks used to store code both in serial execution code sequences and code sequences utilizing address translation. The remapping of bad blocks/sectors in nonvolatile memory allows nonvolatile memory in computer systems to be robust and resilient in handling bad blocks.
