Dynamic remapping of cache lines

A method of managing cache memory includes accessing a cache memory at a primary index that corresponds to an address specified in an access request. A determination is made that accessing the cache memory at the primary index does not result in a cache hit on a cache line with an error-free status. In response to this determination, the primary index is mapped to a secondary index and data for the address is written to a cache line at the secondary index.

Detecting and correcting hard errors in a memory array

Hard errors in the memory array can be detected and corrected in real-time using reusable entries in an error status buffer. Data may be rewritten to a portion of a memory array and a register in response to a first error in data read from the portion of the memory array. The rewritten data may then be written from the register to an entry of an error status buffer in response to the rewritten data read from the register differing from the rewritten data read from the portion of the memory array.
