Transaction log recovery

摘要

The present disclosure includes methods for transaction log recovery in memory. One such method includes examining a number of entries saved in a transaction log to determine a write pattern, reading the memory based on the write pattern, updating the transaction log with information associated with data read from the memory based on the write pattern, and updating a logical address (LA) table using the transaction log.

主权项

1. A method for transaction log recovery, comprising:
determining a write pattern by examining a number of entries in a transaction log; determining locations in memory for each of a number of portions of data that were written to the memory based on the write pattern, wherein location information associated with the number of portions of data is missing from the number of entries in the transaction log; updating the transaction log with location information read from pages that include the number of portions of data, wherein the information is read from the pages in an order based on the write pattern; and updating a logical address (LA) table with location information missing from the LA table after a power interruption using the updated transaction log.
