    摘要: The present disclosure provides methods and circuits for managing failing sectors in a non-volatile memory. A record address and a read control signal are received, where the record address identifies a location in the non-volatile memory. The record address is compared with a plurality of dead sector addresses, where the dead sector addresses correspond to a subset of sectors located in the non-volatile memory. Data located at the record address is determined to be invalid in response to a combination of a first detection that the record address matches one of the dead sector addresses and a second detection that the read control signal indicates a read operation is requested to be performed on the non-volatile memory.

    摘要: Adaptive error correction for non-volatile memories is disclosed that dynamically adjusts sense amplifier read detection windows. Memory control circuitry uses error correction code (ECC) routines to detect bit errors that are non-correctable using these ECC routines. The memory control circuitry then dynamically adjusts sense amplifier read detection windows to allow for correct data to be determined. Corrected data can then be output to external circuitry. The corrected data can also be stored for later access when subsequent read operations attempt to access address locations that previously suffered bit failures. The adaptive error correction can also be used with respect to memories that are not non-volatile memories.

    摘要: A semiconductor memory device comprises a volatile memory and a non-volatile memory including a plurality of sectors. Each of the plurality of sectors configured to store a sector status indicator and a plurality of data records. A control module is coupled to the non-volatile memory and the volatile memory. The control module manages the sectors by scanning the sectors to identify the records with invalid data; changing the status indicator of a particular sector when all of the records in the particular sector are invalid, and discontinuing scanning the particular sector while all of the records in the particular sector are invalid.
