Latest Patents

Ouyang's latest patents include a data storage device and a storage control method based on a log-structured merge tree. This invention relates to a data storage device that utilizes a log-structured merge tree comprising a plurality of SST files stored on at least one storage medium. The storage control method involves using a first filter to obtain the SST file set matched by the query key and a second filter to globally sort the matching tags in the SST file set to generate a global tag set. This method selects SST files to perform file I/O operations to read key-value pairs, thereby reducing the number of file I/O operations in data reading operations and improving file I/O efficiency.

Another notable patent focuses on reducing read command latency in storage devices. This invention describes a storage device, such as a NAND flash device, that includes a controller assigning host read commands to a high priority queue while all other I/O commands, including host write commands, are assigned to a low priority queue. The controller executes commands in the high priority queue before those in the low priority queue, allowing for interleaving of host read commands with execution of page write commands.
