Abnormal power loss recovery method for memory storage device
A recently granted patent (Publication Number: US11907059B2) discloses an abnormal power loss recovery method designed for a memory storage device equipped with a rewritable non-volatile memory module. The method involves reading data from a specific super-physical unit without a corresponding RAID ECC code after an abnormal power loss event, copying this data to another super-physical unit, and implementing various checks and procedures based on the amount of written data and the type of physical units involved. The method aims to ensure data integrity and recovery in the event of power loss, enhancing the reliability of the memory storage device.
Furthermore, the patent also covers a memory control circuit unit responsible for managing the memory storage device, including reading and copying data during abnormal power loss scenarios. The circuit unit interfaces with the host system and the memory module, implementing similar data recovery procedures as outlined in the method claims. By incorporating these features into the memory control circuit unit, the patent aims to provide a comprehensive solution for handling abnormal power loss events in memory storage devices, ultimately improving data protection and system reliability. This innovation underscores the importance of robust power loss recovery mechanisms in ensuring the integrity and stability of data stored in memory devices.
