Abstract
Systems and methods for configuring, controlling and operating a non-volatile cache are disclosed. A host system may poll a memory system as to the memory system's configuration of its non-volatile cache. Further, the host system may configure the non-volatile cache on the memory system, such as the size of the non-volatile cache and the type of programming for the non-volatile cache (e.g., whether the non-volatile cache is programmed according to SLC or the type of TRIM used to program cells in the non-volatile cache). Moreover, responsive to a command from the host to size the non-volatile cache, the memory system may over or under provision the cache. Further, the host may control operation of the non-volatile cache, such as by sending selective flush commands.
