Abstract
Apparatuses, systems, and methods are disclosed for caching data. A method includes directly mapping a logical address of a backing store to a logical address of a non-volatile cache. A method includes mapping, in a logical-to-physical mapping structure, the logical address of the non-volatile cache to a physical location in the non-volatile cache. The physical location may store data associated with the logical address of the backing store. A method includes removing the mapping from the logical-to-physical mapping structure in response to evicting the data from the non-volatile cache so that membership in the logical-to-physical mapping structure denotes storage in the non-volatile cache.
