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.

A semiconductor package such as a multi-chip package is disclosed. The semiconductor package may be configured for dual second level interconnection onto a printed circuit board of a host device. Thus, a single semiconductor package may be used on host printed circuit boards having different configurations.

A data retention operation is performed in a non-volatile memory in response to detection of a triggering event. The data retention operation includes updating a value of a write parameter of the non-volatile memory and storing into the non-volatile memory at least one copy of contents of a boot portion of the non-volatile memory using the updated value of the write parameter. The updated value of the write parameter increases retention of stored data during extended periods of inactivity at the non-volatile memory.
