摘要： A system and method for adjusting read threshold voltage values, for example, in a read circuit internal to a memory device. The quality of an associated read result may be estimated for each read threshold voltage value used to read memory cells. Only read results estimated to have sufficient quality may be allowed to pass to storage. The read threshold voltage value may be adjusted for subsequent read operations, for example, if the associated read result is estimated to have insufficient quality. The read threshold voltage value may be iteratively adjusted, for example, until a read result is estimated to have sufficient quality.

摘要： A method, system and computer-readable medium are provided for reading information from a memory unit. A read instruction may be received to read information from a set of memory cells in the memory unit. A data structure storing sets of read thresholds may be searched for a set of read thresholds based on one or more characteristic value(s) of the set of memory cells. If the set of read thresholds is found, the set of memory cells may be read to execute the read instruction using the found set of read thresholds. The set of read thresholds may be thresholds which were previously used to successfully read a set of cells having the same or similar characteristic value(s).
