Solid State Storage Data Recovery via RAID XOR

The patent applies preliminary action by pre-calculating and storing redundant data in memory locations before defects occur. The system proactively creates backup copies of data in alternative locations, so when a memory location fails, the data can be immediately recovered from the pre-prepared redundant copies without waiting for defect detection or requiring complex real-time recovery operations.

The patent implements copying by creating redundant copies of data across multiple memory locations. Instead of storing data in a single location, the system maintains copies in multiple places, allowing recovery when one or more locations become defective. This copying strategy ensures that the loss of information in defective locations can be compensated by retrieving data from intact copies.

The patent applies segmentation by dividing the memory system into multiple independent memory targets or blocks, each capable of storing redundant data. This segmentation allows the complex redundancy management to be distributed across separate memory units rather than requiring a monolithic complex system. Each memory target can be independently managed and accessed during recovery operations.

The patent implements universality by designing memory locations and control circuitry to serve multiple functions - normal data storage and redundant data storage. The same memory infrastructure is used for both primary and backup data, eliminating the need for separate dedicated recovery hardware. This multi-functionality reduces overall device complexity while maintaining data recovery capabilities.

The patent applies preliminary action by pre-positioning redundant data in memory locations ready for immediate retrieval. When data recovery is needed, the system can immediately access the pre-stored redundant copies without performing time-consuming calculations during the recovery process. This pre-preparation significantly reduces the processing time required for data reconstruction while maintaining accuracy.

The patent implements copying by creating exact copies of data that can be directly retrieved and used for reconstruction. Instead of performing complex real-time calculations to reconstruct data, the system retrieves pre-copied data copies that are already ready. This copying approach maintains data reconstruction accuracy while dramatically reducing processing time compared to computational reconstruction methods.
