SYSTEMS AND METHODS FOR STORING, RETRIEVING, AND ADJUSTING READ THRESHOLDS IN FLASH MEMORY STORAGE SYSTEM

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).
