U.S., French Inventors Develop Memory Usage Optimization Method with Data Lifetimes

ALEXANDRIA, Va., May 9 -- Robert S. Schreiber of Palo Alto, Calif., and Alain Darte of Lyons, France, have developed a method of storing data.

According to the U.S. Patent & Trademark Office: "A method of storing data includes the steps of storing data comprising the steps of identifying respective lifetimes of each member of an indexed collection of data elements, each of the data elements referenceable in a data index space representing a set of valid data element indices; identifying a set of pairs of the data elements having overlapping lifetimes; and generating a mapping from the data index space to an address offset space based on the set of pairs of the data elements having the overlapping lifetimes."

The inventors were issued U.S. Patent No. 7,363,459 on April 22.

The patent has been assigned to Hewlett-Packard Development Co. LP, Houston.

The original application was filed on Oct. 31, 2002, and is available at: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=7,363,459.PN.&OS=PN/7,363,459&RS=PN/7,363,459.
