Nanjing University Assigned Patent

Nanjing University, Nanjing, China, has been assigned a patent (10,185,657) developed by Zhang, Qi, Li, Xuandong, Wang, Linzhang, and Zhang, Tian, Nanjing, China, for “method and system for optimizing deterministic garbage collection in NAND flash storage systems“.

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method for partial garbage collection in a NAND flash storage system is disclosed. The method includes receiving a real time data request task in a NAND flash storage system, executing the real time data request task in the NAND flash storage system, determining a condition whether a number of free pages in the NAND flash storage system is below a pre-determined threshold, for the condition that the number of free pages in the NAND flash storage system is below a pre-determined threshold, determining whether a partial garbage collection list is empty, for the condition that the partial garbage collection list is empty, selecting a victim block from a plurality of blocks in the NAND flash storage system, creating partial garbage collection tasks in the NAND flash storage system, and putting the partial garbage collection tasks in the partial garbage collection list”.

The patent application was filed on April 13, 2016 (15/098,133).
