Abstract
Exemplary methods, apparatuses, and systems include identifying that a first cache line from a first cache is subject to an operation that copies data from the first cache to a non-volatile memory. A first portion of the first cache line stores clean data and a second portion of the first cache line stores dirty data. A redundant copy of the dirty data is stored in a second cache line of the first cache. In response to identifying that the first cache line is subject to the operation, metadata associated with the redundant copy of the dirty data is used to copy the dirty data to a non-volatile memory while omitting the clean data.
