Storing data to host system memory upon entry of a memory system non-operational power state

A memory system, comprising:

• one or more components configured to:
• store context data of the memory system in a buffer located in a host system volatile memory during entry of the memory system into a non-operational power state,
• wherein the context data includes state information to be used for resumption of memory system operations without reinitialization of the memory system;
• and
• retrieve the context data from the buffer upon exiting the non-operational power state.

A solid-state drive (SSD), comprising:

• one or more components configured to:
• allocate a portion of a host system volatile memory as a host allocated drive state memory (HADSM) buffer for storing context data associated with the SSD when the SSD is in a non-operational power state;
• determine a set of context data stored in an SSD volatile memory that is to be preserved when the SSD is in the non-operational power state;
• and
• write the set of data to the HADSM buffer prior to entering the non-operational power state.
