摘要
A method for analyzing a read error event is provided comprising reading a page of data stored in memory, determining a read error event for the page of data, and identifying a scope of the read error event in the memory. In another embodiment, a method for performing a preliminary read error recovery is provided comprising reading a first data unit from memory and identifying a bit error rate for a first data unit with a correction engine, determining that the bit error rate is above a threshold, accessing a data structure including entries identifying data units and read error event information associated with the data units, identifying a second data unit in an entry that matches the first data unit, and performing a preliminary read error recovery process on the first data unit using the information in the entry to reduce the bit error rate below the threshold.
