MEMORY SYSTEM STORING MANAGEMENT INFORMATION AND METHOD OF CONTROLLING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18645697 titled 'MEMORY SYSTEM STORING MANAGEMENT INFORMATION AND METHOD OF CONTROLLING SAME
Simplified Explanation: The memory system described in the patent application includes a management-information restoring unit that detects short breaks in a NAND memory by analyzing pre-logs and post-logs. When a short break is identified, the unit restores management information using selected logs and performs recovery processing on all write-once blocks in the memory.
- The management-information restoring unit detects short breaks in a NAND memory by analyzing pre-logs and post-logs.
- It restores management information using selected logs after identifying a short break.
- Recovery processing is applied to all write-once blocks in the memory to ensure data integrity.

Original Abstract Submitted
A memory system includes a management-information restoring unit. The management-information restoring unit determines whether a short break has occurred referring to a pre-log or a post-log in a NAND memory. The management-information restoring unit determines that a short break has occurred when the pre-log or the post-log is present in the NAND memory. In that case, the management-information restoring unit determines timing of occurrence of the short break, and, after selecting a pre-log or a post-log used for restoration, performs restoration of the management information reflecting these logs on a snapshot. Thereafter, the management-information restoring unit applies recovery processing to all write-once blocks in the NAND memory, takes the snapshot again, and opens the snapshot and the logs in the past.
