Introduction

Song Liu is an accomplished inventor based in Fremont, CA (US). He has made significant contributions to the field of technology, particularly in the area of solid-state drives and file storage systems. With a total of 3 patents to his name, Liu's work has had a notable impact on data storage solutions.

Latest Patents

One of Liu's latest patents is titled "Performance penalty avoidance for solid state drive." This invention involves a host computer that is coupled to a solid-state drive (SSD). The filesystem of the host computer can receive a write pointer from the firmware of the SSD, which references the next available page in an erase block. In response to a file write request, the filesystem determines a logical address range to store a portion of the target file based on the write pointer. It then generates a sector write command to send to the SSD, specifying the determined logical address range.

Another significant patent by Liu is "File storage system based on coordinated exhaustible and non-exhaustible storage." This system coordinates non-exhaustible and exhaustible storage devices, where exhaustible devices are lower-grade flash-based storage. The non-exhaustible devices utilize magnetic recording mechanisms or higher-grade flash storage. The system optimizes content items on exhaustible storage devices, ensuring that more frequently accessed items are moved to devices with fewer data operations, thereby prolonging their operational lifetime.
