(Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service
ALEXANDRIA, Va., Sept. 26 -- Super Talent Electronics, San Jose, Calif., has been assigned a patent (8,543,742) developed by Frank Yu, Palo Alto, Calif., Abraham C. Ma, Fremont, Calif., and Shimon Chen, Los Gatos, Calif., for a "flash-memory device with RAID-type controller."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A smart flash drive has one or more levels of smart storage switches and a lower level of single-chip flash devices (SCFD's). A SCFD contains flash memory and controllers that perform low-level bad-block mapping and wear-leveling and logical-to-physical block mapping. The SCFD report their capacity, arrangement, and maximum wear-level count (WLC) and bad block number (BBN) to the upstream smart storage switch, which stores this information in a structure register. The smart storage switch selects the SCFD with the maximum BBN as the target and the SCFD with the lowest maximum WLC as the source of a swap for wear leveling when a WLC exceeds a threshold that rises over time. A top-level smart storage switch receives consolidated capacity, arrangement, WLC, and BBN information from lower-level smart storage switch. Data is striped and optionally scrambled by Redundant Array of Individual Disks (RAID) controllers in all levels of smart storage switches."
The patent application was filed on June 12, 2012 (13/494,409). The full-text of the patent can be found 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=8543742.PN.&OS=PN/8543742&RS=PN/8543742
