Lite-On Electronics (Guangzhou) Ltd., Guangzhou, China, and Lite-On Technology Corporation, Taipei, Taiwan, has been assigned a patent (9,747,973) developed by Lee, Ming-Hsuan, Chuang, Sen-Ming, and Liu, Jen-Cheng, Taipei, Taiwan, for a "solid state storage device and data writing method to prevent data loss during program cycle."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A data writing method for a solid state storage device includes following steps. A step, (a) is performed to judge whether a shutdown command is issued from a host. In a step, (b), if the solid state storage device confirms that the shutdown command is not issued from the host, plural program procedures are performed. Consequently, plural write data in a buffer are stored to a triple-level cell flash memory according to a program order. In a step, (c), if the solid state storage device confirms that the shutdown command is issued from the host, plural redundant data are added to the plural write data, the write data are stored into the buffer, and the plural program procedures are performed. Consequently, the plural write data in the buffer are stored to the triple-level cell flash memory according to the program order."

The patent application was filed on January 11, 2016 (14/992,285).
