Dataram, Inc., Bellevue, WA, has been assigned a patent (8,838,903) developed by Jason Caulkins, West Windsor, NJ, for a “priority ordered multi-medium solid-state storage system and methods for use.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A hierarchical data-storage system has a volatile storage medium, a first non-volatile storage medium, and a controller including a ranking engine tracking data writes to each of the memory mediums. Each medium is associated with a pre-set capacity threshold, and the controller, upon the volatile medium reaching its pre-set threshold, identifies one or more blocks of data as least-frequently written to the volatile medium, copies the data in those blocks to the non-volatile medium, and marks those blocks as available for new data writes, and the controller, upon the non-volatile medium reaching its pre-set threshold, identifies one or more blocks of data as least-frequently written to the non-volatile medium, and marks those blocks as available for new data writes from the volatile medium.”

The patent application was filed on Feb. 4, 2010 (12/700,206).
