HoneycombData Assigned Patent

HoneycombData, Inc., Santa Clara, CA, has been assigned a patent (9,891,833) developed by Devendrappa, Sushma, San Jose, CA, Ouyang, Xiangyong, South San Francisco, CA, and Yoon, Jongman, San Jose, CA, for an “eliminating garbage collection in NAND flash devices.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A storage device, such as a NAND flash device, avoids the need for garbage collection. An application executing on a host system tracks data objects that are marked as invalid and maintains an association between data objects and logical blocks, each logical block corresponding to a physical block of memory in the NAND flash device. Upon determining that the logical block contains no valid objects, the application instructs an SSD to trim the physical block of memory corresponding to the logical block. The application also aggregates write commands until a full block of data is ready to be written, at which point the application transmits a write command to the SSD.”

The patent application was filed on October 22, 2015 (14/920,617).
