AI Technical Summary
Existing SSD error correction methods lack flexibility, cannot dynamically adjust error correction strategies, cannot effectively cope with voltage drift, lack prediction and management of bad blocks, leading to an increased risk of data loss, and lack of multi-dimensional analysis when evaluating error correction performance, affecting system real-time performance.
By acquiring error bit statistics of data blocks, an error correction strength level is generated, soft-decision iterative decoding is performed, voltage drift is calculated and reference voltage is corrected, a bad block prediction table is established, an error correction feature knowledge base is constructed, and data matching and repair are carried out.
It improves data integrity and reliability, reduces the risk of data loss, enhances error correction efficiency and data recovery success rate, ensures data reading accuracy, and provides multi-dimensional error correction performance evaluation and preventive maintenance.
