Claim 7:
8. A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:
detect an operation to write dirty data to a cache, wherein the cache is divided into a plurality of channels and further divided into a plurality of sets addressed via set values;
write the dirty data to a first cache line in the cache, wherein the first cache line is accessed via a first channel;
select a second cache line for writing a redundant copy of the dirty data, wherein the second cache line is accessed via a second channel and selected because the first and second cache lines have a same set value on different channels; and
write the redundant copy of the dirty data to the second cache line in the cache, wherein the second cache line serves as a redundant write buffer.
