Variable data recovery scheme hierarchy
Abstract:
Method and apparatus for managing data in a memory, such as a flash memory. In accordance with some embodiments, a memory has a plurality of solid-state non-volatile memory cells. A processing circuit is connected to the memory and configured to direct the execution of a plurality of read error recovery routines in response to at least one uncorrectable read error in a data set retrieved from the memory. The recovery routines are executed in a selected order based on an elapsed recovery time parameter for each of the recovery routines and an estimated probability of success of each of the recovery routines.
