Latest Patents

Song’s patent, “High-speed compute express link storage transfer,” describes a storage device, an operating method, and a storage system. The device uses a first memory to hold data and a second memory to store a bitmap that identifies whether data in the first memory is dirty.

When the storage controller receives a transfer command from a CXL switch, it uses the bitmap to pre-fetch dirty data from the first memory into the second memory. The controller also sends the switch a request to flush cache at one or more other external devices connected to the switch. This approach coordinates data transfer and cache management across the CXL-connected system.

Career Highlights

Song’s listed patent reflects work on storage systems that use CXL connectivity to transfer data between devices. The invention focuses on identifying dirty data, preparing it for transfer, and coordinating cache flushing through a CXL switch.

Collaborations

Song’s listed coworker is Won Seb Jeong. The patent information provided identifies Samsung Electronics Co., Ltd. as Song’s company.

Conclusion

Hyeon Ho Song’s patent addresses coordinated, high-speed storage transfer by combining bitmap-based dirty-data identification, pre-fetching, and cache-flush requests in a CXL-connected system.
