Media manager cache with integrated drift buffer

A system for caching read and write memory requests while accounting for a phase change memory cell drift phenomenon, the system comprising:

• a cache to include a first set of entries and each entry in the first set of entries includes user data;
• a media manager cache content-addressable memory (CAM) to include a second set of entries, wherein each entry in the second set of entries includes a reference to an entry in the first set of entries;
• and
• a drift CAM to include a third set of entries, wherein each entry in the third set of entries includes a reference to an entry in the first set of entries.

A system comprising:

• a memory component;
• and
• a processing device, coupled to the memory component, configured to:
• add, in response to receiving a write memory request from a host system, an entry to a cache that includes user data of the write memory request, wherein the write memory request is directed to a set of phase change memory cells;
• add, in response to receiving the write memory request, an entry in a first content-addressable memory (CAM), wherein the entry in the first CAM includes a reference to the entry in the cache that includes the user data of the write memory request;
• write the user data of the write memory request to the set of phase change memory cells;
• add an entry to a second CAM, wherein the entry in the second CAM includes a reference to the entry in the cache that includes the user data of the write memory request;
• and
• evict the entry in the first CAM such that the entry in the cache is referenced by the second CAM.
