Nuvoton Technology Assigned Patent

Nuvoton Technology Corporation, Hsinchu, Taiwan, has been assigned a patent (9,811,473) developed by Lu, Chia-Ching, Hsinchu, Taiwan, for a “storage unit controller and control method thereof, and storage device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A storage unit controller and a control method thereof, and a storage device are provided. The storage unit controller includes an address mapping unit, a nonvolatile buffer and an update indicator. The update indicator sets an indicated flag according to whether a first data saved in the nonvolatile buffer is written to a storage unit. The address mapping unit checks the indicated flag when power is on. When the checked indicated flag indicates that writing the first data is not completed, the address mapping unit enables an update operation mode so as to perform background operations: the first data has not yet been successfully addressed to the storage unit previously, but saved in a simulated address of the nonvolatile buffer to transfer the first data from the simulated address to an actual address of the storage unit.”

The patent application was filed on September 4, 2014 (14/476,758)
