High-performance storage structures and systems featuring multiple non-volatile memories

摘要

A memory storage system that includes at least a storage controller, a first non-volatile, solid-state memory and a second non-volatile, solid-state memory. The storage controller has an interface to receive commands from a host system. The first non-volatile, solid-state memory device is coupled with the storage controller to at least store data received from the host system. The second non-volatile, solid-state memory is coupled with the storage controller to store context information corresponding to the data stored in the first non-volatile, solid-state memory device.

1. An apparatus comprising:
a storage controller having an interface to receive commands from a host system; a first non-volatile, storage device coupled with the storage controller, the first non-volatile storage device to store data received from the host system; a non-volatile, solid-state memory device coupled with the storage controller, the non-volatile, solid-state memory device to store context information for data stored in the first non-volatile storage device, wherein periodic back-up stores of the context information into the first non-volatile storage device are substantially avoided on account of the context information being kept in non volatile memory, wherein the first non-volatile storage device is comprised of a different type of non volatile storage technology than what that the non-volatile, solid state memory device is comprised of.
