Shannon Systems Ltd., Shanghai, China, has been assigned a patent (9,997,209) developed by Zhou, Zhen, Shanghai, China, and Yang, Xueshi, Cupertino, CA, for a “power-failure protection method and solid state drive.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Provided are a power failure protection method and solid state drive, (SSD). The SSD comprises: a power-failure detection device, for monitoring in real time whether the power supply is abnormal, a power-failure protection device performs a power-failure protection operation when the power supply is monitored to be abnormal: breaking a connection with a host system bus, an SSD internal clock breaking from a system bus clock and writing data in the SSD cache into a storage unit of the SSD by using the SSD internal clock. The technical solution ensures completion of the data protection operations by utilizing a remaining capacity, thus ensuring data integrity.”

The patent application was filed on January 8, 2015 (15/527,538).
